[PATCH] D38318: [X86][SSE] Match PSHUFLW/PSHUFHW + PSHUFD vXi16 shuffle patterns (PR34686)

[Elena Demikhovsky via Phabricator via llvm-commits]

delena added a comment.

In this case we need to add "SlowShuffle.." property to these two targets. I don't see any other way to distinguish. Or "Fast" to HSW, but I suggest the fist variant, because less instructions is more obvious.
