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.

dfd2bcbd3c [flang] Undo previous commit. 
`name` depends on the template type, so we have to explicitly say
that `has` is a template with the `template` keyword.
Rather than do that I'm putting back the explicit type for name.

744427238c [flang] Rewrite function calls to array element references 
parse-tree.h, parse-tree.cc:
Add FunctionReference::ConvertToArrayElementRef() to convert a function
reference to an array element reference.
Factor out MakeArrayElementRef() to use in ConvertToArrayElementRef()
and also in converting statement functions to array element assignments.

resolve-names.cc:
Recognize references to functions and subroutines and add symbols for them.
Detect declaration conflicts from these and check `IMPLICIT NONE(EXTERNAL)`.

rewrite-parse-tree.cc:
Find function references that need to be converted and rewrite them.

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.
