PATCH: Yet another ObjC-ish "hook" in c-decl.c

[Ziemowit Laski <zlaski at apple dot com>]

A recent modification to store_parm_decls() broke the ongoing ObjC 
integration
again :-(.  In its new form, store_parm_decls() is no longer usable 
from ObjC,
because it dereferences the newfangled 'current_function_arg_info' 
static variable,
which only grokdeclarator() sets.  The new objc-act.c no longer calls 
any of the
grok...() functions, since it no longer deals in raw declspec goo.

So, I introduce process_parm_decls(), which future ObjC will call 
instead
of store_parm_decls().  I'm inclined to commit this as obvious since 
this
solves ObjC's problems and cannot possibly cause any problems for C, 
but I'll
wait a short while for people's thoughts, if any.
