[PATCH i386 AVX512] [74/n] Add byte/word max/mix reduction.

[Kirill Yukhin]

Hello,

Bootstrapped.
AVX-512* tests on top of patch-set all pass
under simulator.

Is it ok for trunk?

gcc/
        * config/i386/i386.c
        (emit_reduc_half): Handle V64QI and V32HI mode.
        * config/i386/sse.md
        (define_mode_iterator VI_AVX512BW): New.
        (define_expand "reduc_<code>_<mode>"): Use VI512_48F_12BW.

Thanks, K
