[PATCH i386 AVX512] [80/n] Extend expand_sse2_mulvxdi3.

[Kirill Yukhin]

Hello,
This patch extends expand_sse2_mulvxdi3.

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

Is it ok for trunk?

gcc/
        * config/i386/i386.c (ix86_expand_sse2_mulvxdi3): Extend
        expand_sse2_mulvxdi3.

Thanks, K
