mescc: Add __SIZEOF defines for int, long, long long.

Browse source 
* module/mescc/mescc.scm (arch-get-define): Rename
to...  (arch-get-defines): ...this.  Return a list of defines: Also
adding __SIZEOF_INT__, __SIZEOF_LONG__, and add __SIZEOF_LONG_LONG__ if
it's >=8.
(mescc:preprocess, c->info): Update callers.
* include/stdint.h[!__SIZEOF_LONG_LONG__]: Remove typedefs for int64_t,
uint16_t.
