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;


Fixed in r68015.
