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.

Work on scanning compiler directive lines.
Fix glitch in earlier change to parse-state.h.
Add ClassifyLine(), simplify some token sequence data lifetimes and interfaces.
Handle continued directives. Obey !DIR$ FIXED and FREE in prescanner.
Some refactoring of TokenSequence API, then support initial directives (FIXED, FREE, IGNORE_TKR).
Fix !DIR$ IGNORE_TKR syntax, manual was wrong.
Debugging directive scanning & parsing.
Profiling-directed speed-up - do not map cooked source locations to Provenance until a Message is emitted. Turn some non-nullable pointers into references.
Debugging.
Handle !DIR$ IVDEP too, it is in a test.
Accept directives in the execution part.

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.

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.
