[PATCH, i386]: Remove VI_512 mode iterator ...

[Uros Bizjak]

... and use equivalent VI_AVX512BW mode iterator instead.

No functional changes.

2016-12-27  Uros Bizjak  <ubiz...@gmail.com>

    * config/i386/i386.md (VI_512): Remove.
    (vcond<V_512:mode><VI_AVX512BW:mode>): Use VI_AVX512BW
    mode iterator instead of VI_512.
    (vcondu<V_512:mode><VI_AVX512BW:mode>): Ditto.

Bootstrapped and regression tested on x86_64-linux-gnu {,-m32}.

Committed to mainline SVN.

Uros.
