About 1.5 years ago I tested AVX2 speed increase on Haswell

I can relatively easily install Clang on Linux.

Currently cpu.h lacks FLAC__SSE_TARGET and FLAC__SSEnn_SUPPORTED
macros for clang. I added them, but I cannot properly test them
as I can't get compiled flac.exe under Windows (don't know
how to setup clang under MSYS2).
If somebody has working clang, please test this patch.
Does it affect
