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.

9f755666fb [flang] Add ENUM_CLASS to define enum class with ToString function. 
This replaces DEFINE_NESTED_ENUM_CLASS in parse-tree.h but works
similarly. "ENUM_CLASS(Foo, A, B, C)" defined enum class Foo with
enumerators A, B, C. It also defines an overloading of EnumToString
that converts enumerators to their string representation.

Change unparse.cc to adapt to this change.

Make use of ENUM_CLASS in attr.h and attr.cc.

03aecfc336 [flang] Preserve some minor changes that accumulated as I was implementing 
an unparsing feature.

Enum classes in parse tree node class types are now defined with
a macro so that the names of the enumerations can be captured for
formatting purposes.

Add a TODO comment.

Rebase to new master with parse tree traversal code.

66c9a69a61 [flang] Fix classes with variant and other fields 
Fortran::FormatItem and UseStmt have both normal fields and a variant
named 'u'. The Walk calls for the normal fields were missing.
These were the only two classes I found where this occurs.

2af29bc1e2 [flang] Add Unparse function. 
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.

0406170acb [flang] Reorder the Walk functions. 
Group the Walk functions that call WalkTupleClass, WalkUnionClass,
WalkWrapperClass all together, after the ones that don't follow a
simple pattern like that.

Fix the name of the include guard macro.

686529a59a [flang] Add some missing Walk functions. 
The classes in parse-tree.h that used WRAPPER_CLASS_BOILERPLATE were
accidentally omitted.

Also remove the anonymous namespace around utilities like
WalkWrapperClass as they can be useful outside this file too.

2ca306abe1 [flang] Rename "visit" to "Walk" to avoid conflict with std::visit. 
The thing called on each parse tree node during the walk is still
referred to as a visitor.

Change "pre" to "Pre" and "post" to "Post" to follow the naming
conventions.
