[PATCH mm] kasan, powerpc: Don't rename memintrinsics if compiler adds prefixes

With appropriate compiler support [1], KASAN builds use __asan prefixed meminstrinsics, and KASAN no longer overrides memcpy/memset/memmove. If compiler support is detected (CC_HAS_KASAN_MEMINTRINSIC_PREFIX), define memintrinsics normally (do not prefix '__'). On powerpc, KASAN is the only user o
