[x86] AVX FP compare builtins should require AVX target feature (PR28112)
This is a fix for PR28112:
https://llvm.org/bugs/show_bug.cgi?id=28112
The FP comparison intrinsics that take an immediate parameter (rather than specifying
a comparison predicate in the function name) were added with AVX; these are macros in
avxintrin.h. This patch makes clang behavior match gcc (error if a program tries to use
these without -mavx) and matches the Intel documentation, eg:
VCMPPS: m128 _mm_cmp_ps(m128 a, __m128 b, const int imm)
'V' means this is intended to only work with the AVX form of the instruction.
