pixman: drop support for MMX on x86
LLVM has dropped the ability to generate vectorized code using compiler
intrinsics for chips with MMX but without SSE2. The pixman library
detects available CPU features at runtime and will either fall back
to the generic implementation or use the SSE2 or SSSE3 code paths.

Define CARD64 as unsigned long long on OpenBSD LP64 to match uint64_t.
This fixes a number of errors with llvm 22 where X code mixes
CARD64 and uint64_t. ok tb@
