[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.

Add support for the always_inline + target feature diagnostic to print

out the first missing target feature that's required and reword
the diagnostic accordingly.

Provide a frontend based error for always_inline functions that require

target features that the caller function doesn't provide. This matches
the existing backend failure to inline functions that don't have
matching target features - and diagnoses earlier in the case of
always_inline.

Fix up a few test cases that were, in fact, invalid if you tried
to generate code from the backend with the specified target features
and add a couple of tests to illustrate what's going on.

This should fix PR25246.
