I forgot that all avx2 functions are inside "#ifdef FLAC__AVX2_SUPPORTED" conditional, so they simply don't exist if FLAC__AVX2_SUPPORTED is not set. Anyway, stream_encoder_intrin_avx2-after.txt shows that the code contains AVX2 instructions such as vpabsd/vpaddd/vphaddd, so this function was compiled properly.

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 en/decoding speed? Or at least, dows it affect disassembly of functions such as
