[PATCH] D114779: [LV] Remove `LoopVectorizationCostModel::useEmulatedMaskMemRefHack()`

[Bardia Mahjour via Phabricator via llvm-commits]

bmahjour added a comment.

Even though the initial intention of the "hack" might have been to prevent predication on some X86 subtargets, it was added in a way that affected all targets, so it could expose cost model issues on various targets if suddenly removed. I wasn't aware of this and just noticed it....has any performance runs been done on other targets (eg. Power)?
