Subject: [X86] Merge VMOVMSKBrr and MOVMSKBrr in the SNB sheduler model.
X-Git-Tag: llvmorg-7.0.0-rc1~9858
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7f142b8bf1b73495bd53687a7ae2698e1106e3e3;p=platform%2Fupstream%2Fllvm.git

[X86] Merge VMOVMSKBrr and MOVMSKBrr in the SNB sheduler model.

The VMOVMSKBrr was in a separate InstRW with a lower latency, but I assume they should be the same and the higher latency matches Agners table so I'm going with that.
