Recognize modules and open and close the corresponding scope.
Handle PUBLIC and PRIVATE statements and set the corresponding
attributes on entity declarations in the module.
Refactoring (no functional changes): Make CheckImplicitSymbol() and
GetVariableName() overloadings private and out-of-line.
Add missing option to f18 help.

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.

"f18 -fdebug-resolve-names -fparse-only ..." is equivalent to what
test-type used to do, so the test-type executable can be eliminated.
-fdebug-dump-parse-tree does the parse-tree dumping that test-sema
does, but test-sema does more so I have left it alone.

Includes like "../dir/file.h" should sort after local includes.
This change fixes that and applies the new formatting.
Now the order (in reverse) is:
- system includes
- includes from llvm or clang (this is from the default IncludeCategories)
- includes of ../something
- everything else

Clean out old data structure formatter.
Create stand-alone Parsing class to compose parts of the parser together.
Hello, world!
Better error recovery on command line errors.
Fix bugs from initial run at f77_correct.
Allow parentheses on PROGRAM statement.
Fix Hollerith scanning.
Remove REDIMENSION with good error recovery.
Fix new "spaces" parser, clean up calls to it.
Fix bugs exposed by in38.f90.

Reformat C++.
More work on multi-byte source encoding.
Pass 219 tests in f77_correct, with good excuses for the rest.

The classes that were segregated into format-specification.h have
also been grouped into a new Fortran::format namespace.
Code added to tools/f18/f18.cc to run a minimal visitor over
the parse trees resulting from successful parses so that any
future build problems with Walk() will be caught earlier.
Rearrange Walk instances, keep format:: ones together.

Enum classes in parse tree node class types are now defined with

Unparse takes a parse tree and converts it back to Fortran.
class UnparseVisitor implements a parse tree visitor that emits
the appropriate Fortran source for each node that it visits.
It is only partially implemented so far.
Change f18 to dump the parse tree using Unparse.
