[PATCH i386 AVX512] [76/n] Extend int 2 float conversions.

[Kirill Yukhin]

Hello,
This patch extends autogeneration of SI-2-SF
conversions.

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_vector_convert_uns_vsivsf): Handle V16SI mode and
        TARGET_AVX512VL.

Thanks, K
