[PATCH] D42544: [X86][AVX512] Add combining support for X86ISD::VTRUNCS

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon created this revision.
RKSimon added reviewers: zvi, delena, craig.topper, spatel.

Similar to the existing support for X86ISD::VTRUNCUS.

This need to be done before I can add support for PACKSS/PACKUS saturated truncation handling.
