filenames (and also '#pragma GCC dependency' of course).  Now, assuming
no cleaning is needed, we can go all the way from lexing the filename to
doing filename lookups with no mallocs.  This speeds up user PP time from
0.077 to 0.075s for Cocoa.h (2.6%).

This avoids some copying in its clients.

the normal case (or will, when some other stuff is converted over).

- Added basic structure for parsing top level Objective-C forms.
- Extended the typedef mechanism for classes, improved performance of the common case.
- Implemented @class in the parser.
