[debug-early] C++: moving more things before the compilation proper

[Aldy Hernandez]

Hi Jason.

As promised, I am moving most everything out of 
cxx_post_compilation_parsing_cleanups() which is the hook that will be 
called after the compilation proper has run 
(symtab->finalize_compilation_unit()).

Apart from the Java hidden alias support which I just asked you about, 
and the VTV stuff which will remain in the aforementioned hook, the only 
remaining bits are:

  input_location = locus_at_end_of_parsing;

#ifdef ENABLE_CHECKING
  validate_conversion_obstack ();
#endif /* ENABLE_CHECKING */

I am keeping the input_location bit because the final VTV stuff has some 
error() calls which presumably will need a location.

And I am keeping validate_conversion_obstack() because I *think* the VTV 
stuff will create calls?  If not, let me know and I can move this bit too.

In any case, things are pretty deserted in 
cxx_post_compilation_parsing_cleanups(), which should make everybody 
happy :-).

I am committing the following to the branch.  Let me know if you have 
any suggestions.

Thanks.
Aldy
