[cfe-dev] Clang header coexistence

The current implementation of stdint.h in clang conflicts with the
system headers on FreeBSD/i386. Specifically, sys/types.h (and the
system stdint.h) defines intptr_t as int (via two other typedefs) and
clang's stdint.h defines it as long. Both of these are 32-bit signed
integers on IA32, but they are different according to the C type
system and so throw an error preventing compilation of any file that
includes both headers.
I believe the solution to this is to add this in the
FreeBSDX86_32TargetInfo constructor, but I've not looked at this part
of clang in any detail:
IntPtrType = SignedInt;
