9727b06813 [flang] Support for USE statements. 
When a USE statement is encountered, find the scope corresponding to the
module. This is now stored in the ModuleDetails of the module symbol.
useModuleScope_ tracks this while processing the USE. Currently only
modules defined in the same file work because we don't have module files.

At the end of a USE that isn't a use-only, add all public names that
were not renamed.

AddUse() handles recording of a USE by creating a local symbol with
UseDetails that tracks the use-symbol in the module and the location of
the USE (for error messages). If an ambiguous USE is detected, the
UseDetails are replaced by UseErrorDetails. This tracks the locations of
all the uses so that they can be referenced in a diagnostic.

Detect attempts to re-declare use-associated symbols as well as changing
their attributes (except for ASYNCHRONOUS and VOLATILE).

Add missing checks for access-stmt in scoping units other than modules.

Add tests for the new errors.

Reorganize the MessageHandler::Say() overloadings to prevent them from
becoming too numerous.

be1a9990a8 [flang] resolve-names.cc reorganization and cleanup. 
Add ScopeHandle class to manage the stack of scopes and MakeSymbol(), which
makes a symbol in the current scope. Move the call to ApplyImplicitScopes()
into PopScope() as it must be done for each scope.

Add ModuleVisitor class to manage module-related resolution. Currently that
consists of beginning and ending modules and access statements. This is
preparation for further module work.

Replace references to parser::CharBlock with SourceName.

1c291436f5 [flang] Implement parse tree rewriting. 
Add parse-tree-mutator.h like parse-tree-visitor.h except that the Walk
functions take non-const references to parse tree nodes so the Pre and
Post methods of the mutator that are passed around can make changes to
the parse tree.

Change ExecutionPart to be a class that wraps a list so that it can be
identified during parse tree walking.

Add Symbol* field to parser::Name for the result of symbol resolution.
In parse tree dumper, dump symbol when it is there instead of just name.

Add RewriteParseTree to walk the parse tree, fill in resolved symbols in
Name nodes, and make necessary changes to the structure. Currently that
consists of rewriting statement functions as array assignments when
appropriate.

In ResolveNames, call RewriteParseTree if the resolution was successful.
Recognize a statement function that comes after a mis-identified
statement function and report an error. resolve08.f90 tests this case.

Add -fdebug-dump-symbols to dump the scope tree and symbols in each scope.
This is implemented by DumpSymbols in resolve-names.cc. Add an optional
symbol to scopes that correspond to symbols (e.g. subprograms). Remove
debug output from ResolveNamesVisitor as this option can be used instead.

7e34313ff7 [flang] Add statement functions to symbol table 
SubprogramDetails: Store dummy args and result as symbols, not names.

Symbol: Save list of occurrences (i.e. SourceNames that map to the same
symbol). This is needed to map Names in the parse tree back to symbols,
and will probably be useful when reporting errors.
Improve dumping of symbols.

resolve-names.cc: Recognize statement functions. They are treated like
function subprograms but the result type and type of dummy arguments come
from the enclosing scope. The implicit rules from the enclosing scope need
to be copied in.

The method DeclareEntity was extracted out to handle the common part for
EntityDecl, ObjectDecl, and DimensionStmt. AllocatableStmt and TargetStmt
are now handled through their contained ObjectDecl.

The test resolve07 checks the interactions between these kinds of declarations.

Rename ComponentArraySpec to ArraySpec as it doesn't just occur in components.

Fix some 'begin' and 'end' methods to start with upper-case letters.

af2940cfb6 [flang] Continue work on name resolution. 
In Symbol and Scope, use SourceName (== parser::CharBlock) in place of
Name (== std::string) so that names in the symtab have provenance. We
may ultimately have multiple source locations associated with a symbol.

ImplicitRules: Add isImplicitNoneType and isImplicitNoneExternal flags.

MessageHandler: Add methods to emit messages associated with source
locations.

Detect conflicting declarations of symbols (e.g. as subprogram and
variable).

Handle attribute statements like ASYNCHRONOUS statement: make sure the
symbol is present and set the attribute on it. Check that these all have
a type declared by the end of the specification part if IMPLICIT NONE.

Find variables named in Variable and Expr nodes and check they have
types declared if IMPLICIT NONE. Otherwise, make sure they are in the
symtab and apply the implicit type rules at the end of the scope.

Push a scope for MainProgram nodes and add a symbol for the name if it
has one.

Rename Scope::map_type to Scope::mapType

Add tests for errors currently being detected. There is no framework for
running them yet, just source files with the expected errors in
comments.

Maintain stack of ImplicitRules in parallel with the scope stack.
I doesn't have to live as long as the scopes.

Allow for '_', '$', and '@' in ImplicitRules if they come through from
the parser.

da414d7c3f [flang] Collect implicit type rules and report related errors. 
ImplicitRules maintains a mapping of initial character of an identifier
to its implicit type.

ImplicitRulesVisitor visits the ImplicitStmt and related parse tree
nodes and updates the rules.

Emit errors messages in these cases:
- implicit type specified more than once for a letter
- IMPLICIT statement and IMPLICIT NONE in same scope
- IMPLICIT statement and IMPLICIT NONE(TYPE) in same scope
- more than one IMPLICIT NONE in a scope
- IMPLICIT statement with empty range of letters
- IMPLICIT NONE statement after PARAMETER statement
- TYPE or EXTERNAL repeated in an IMPLICIT NONE statement

Also start emitting error messages through the parser::Messages
interface. An instance of Messages is created from the cooked source and
saved in the MessageHandler class. It tracks the source location of the
current statement and provides a way to emit messages associated with
that statement.

86726d8ee4 [flang] Continue work on name resolution 
Enhance DeclTypeSpecVisitor to find derived-type-specs, including with
type parameter values.

Change DerivedTypeSpec so it only needs the name of the derived type,
not the definition, as that isn't necessarily known when we encounter
it.

Fix how memory is managed in DeclTypeSpec: Intrinsic type specs aren't a
problem -- they are one of a few types that live throughout the program.
Derived type specs are dynamically allocated and the memory is owned by
the DeclTypeSpec -- it allocates it when a DeclTypeSpec for a derived
type is created and deletes it when it is destroyed. Pass around
references to TypeSpecs rather than pointers as they can never be null.

In AttrsVisitor, DeclTypeSpecVisitor, ResolveNamesVisitor: make most
functions out-of-line to clean up the class declaration.

In AttrsVisitor, use preprocessor to simplify the simple case of
encountering a parse-tree class causing an attribute to be set.
Handle all such attributes.

Remove old testing code from type.cc.

Remove some of the declarations for IntExpr and IntConst -- they are
only placeholder classes anyway. Don't distinguish kind and length
parameter values.

9f755666fb [flang] Add ENUM_CLASS to define enum class with ToString function. 
This replaces DEFINE_NESTED_ENUM_CLASS in parse-tree.h but works
similarly. "ENUM_CLASS(Foo, A, B, C)" defined enum class Foo with
enumerators A, B, C. It also defines an overloading of EnumToString
that converts enumerators to their string representation.

Change unparse.cc to adapt to this change.

Make use of ENUM_CLASS in attr.h and attr.cc.

424ec7b35b [flang] Handle empty files gracefully. 
Create interval.h.  Use std::size_t instead of bare size_t.  Redefine parser::Name to not be just a bare string.

Break out and rename CharBlock from token-sequence.h for use in the parse tree.

Incremental replacement of name strings with pointers to cooked characters.

Fix case sensitivity problem.

Use new CharBlock encoding to replace strings for real literal constants.

Normalized cooked character stream to lower case.

Simplify parsing now that cooked stream is lower case.  Replace Keyword in parse tree.

Add static_asserts to || and recovery parsers to enforce same result types.

Remove needless TODO comment inserted earlier.

Fix case conversion on prefixed character literals (f90_correct/dc04.f90).

Use CharBlock in user-state.h.

Complete transition from nextChar to nextCh (i.e., always use pointers).

Document extensions.  Begin work on compiler directive lines.

More documentation work.

Reformat prescan.cc.

a3de9d789c [flang] Partial implementation of Symbols and Scopes. 
A Symbol consists of a common part (in class Symbol) containing name,
owner, attributes. Information for a specific kind of symbol is in a
variant containing one of the *Details classes. So the kind of symbol is
determined by the type of details class stored in the details_ variant.

For scopes there is a single Scope class with an enum indicating the
kind. So far there isn't a need for extra kind-specific details as with
Symbols but that could change. Symbols defined in a Scope are stored
there in a simple map.

resolve-names.cc is a partial implementation of a parse-tree walker that
resolves names to Symbols. Currently is only handles functions (which
introduce a new Scope) and entity-decls. The test-type executable was
reused as a driver for this to avoid the need for a new one.

Sample output is below. When each "end function" is encountered the
scope is dumped, which shows the symbols defined in it.

$ cat a.f90
pure integer(8) function foo(arg1, arg2) result(res)
  integer :: arg1
  real :: arg2
contains
  function bar(arg1)
    real :: bar
    real :: arg1
  end function
end function

$ Debug/tools/f18/test-type a.f90
Subprogram scope: 0 children
  arg1:  Entity type: REAL
  bar:  Entity type: REAL
Subprogram scope: 1 children
  arg1:  Entity type: INTEGER
  arg2:  Entity type: REAL
  bar:  Subprogram (arg1)
  foo:  Subprogram (arg1, arg2) result(res)
  res:  Entity type: INTEGER(8)

01580dd19a [flang] Replace raw pointers with std::unique_ptr. 
This simplifies the "delete and set to null" pattern to just a call to
reset(), and "assign and set to null" to a call to std::move.

The ideal would be a custom deleter that throws an error when an
implicit delete happens but not when reset() is called, but I'm not sure
that's possible.
