[PATCH] D75162: [X86][F16C] Remove cvtph2ps intrinsics and use generic half2float conversion (PR37554)

[Simon Pilgrim via Phabricator via llvm-commits]

Herald added projects: clang, LLVM.

This removes everything but int_x86_avx512_mask_vcvtph2ps_512 which provides the SAE variant, but even this can use the fpext generic if the rounding control is the default.

I have a new f16c-intrinsics-upgrade.ll file as well but for some reason git diff is going weird when I try to include it, basically all the ph2ps tests are cut+paste from f16c-intrinsics.ll
