[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.

[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.
