[PATCH v2 6/6] cgcc: removed unneeded predefines for integers

[Luc Van Oostenryck <luc.vanoostenryck@xxxxxxxxx>]

Now that the arch is passed to sparse via '--arch=ARCH',
all predefines for integers and pointers are defined in sparse
itself. So, integer_types() & define_size_t() are now unneeded.

Remove these functions and -D__SIZEOF_POINTER__.

Note: sparc64 had also an entry for 128-bit integers (with
      name 'LONG_LONG_LONG' and suffix 'LLL'); GCC only
      predefines the SIZEOF macros which sparse also does
      (but for all archs). So, it's fine to remove these also.
