[PATCH i386 AVX512] [62/n] Add vpmaddubsw,vdbpsadbw insn patterns.

[Kirill Yukhin]

Hello,
This patch introduces patterns for vpmaddubsw and vdbpsadbw
insn.

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

Is it ok for trunk?

gcc/
        * config/i386/sse.md
        (define_c_enum "unspec"): Add UNSPEC_DBPSADBW, UNSPEC_PMADDUBSW512.
        (define_insn "avx512bw_pmaddubsw512<mode><mask_name>"): New.
        (define_insn "<mask_codefor>avx512bw_dbpsadbw<mode><mask_name>"):
        Ditto.

Thanks, K
