rs6000: Fix up __m64 typedef in mmintrin.h [PR97301]
The x86 __m64 type is defined as:
/* The Intel API is flexible enough that we must allow aliasing with other
vector types, and their scalar components. */
typedef int __m64 __attribute__ ((__vector_size__ (8), __may_alias__));
and so matches the comment above it in that reads and stores through
pointers to __m64 can alias anything.
But in the rs6000 headers that is the case only for __m128, but not __m64.
The following patch adds that attribute, which fixes the
FAIL: gcc.target/powerpc/sse-movhps-1.c execution test
FAIL: gcc.target/powerpc/sse-movlps-1.c execution test
regressions that appeared when Honza improved ipa-modref.
