Clean out old data structure formatter.
Create stand-alone Parsing class to compose parts of the parser together.
Hello, world!
Better error recovery on command line errors.
Fix bugs from initial run at f77_correct.
Allow parentheses on PROGRAM statement.
Fix Hollerith scanning.
Remove REDIMENSION with good error recovery.
Fix new "spaces" parser, clean up calls to it.
Fix bugs exposed by in38.f90.
Escaped \a is not special to pgf90; get slashes around STRUCTURE name right.
Better multi-byte source encoding support in Hollerith.
Reformat C++.
More work on multi-byte source encoding.
Pass 219 tests in f77_correct, with good excuses for the rest.

This simplifies the "delete and set to null" pattern to just a call to
reset(), and "assign and set to null" to a call to std::move.
The ideal would be a custom deleter that throws an error when an
implicit delete happens but not when reset() is called, but I'm not sure
that's possible.

This replaces the manual walking code in test-type.cc. It walks the
parse tree and constructs DeclTypeSpec and DerivedTypeDef objects for
each type encountered. It's in a new file, make-types.cc, so that
failing compilations complete faster.
Handle more parts of derived type definitions.
Also some minor cleanups in type.h and type.cc.

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.

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.

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.

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.
