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.
