07a028098f [flang] Trait-based parse tree traversal. 
Add a CLASS_TRAIT macro to idioms.h to define template metaprogramming
based on definable traits of user-defined classes.  Tweak the boilerplate
macros in parse-tree.h to add traits to the empty, wrapper, union, and
tuple classes in the parse tree.  Replace the macros in parse-tree-visitor.h
with trait-driven templates.

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.
