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.
