[PATCH] D37251: [X86] Add a pass to convert instruction chains between domains

[Guy Blank via Phabricator via llvm-commits]

Herald added a subscriber: mgorny.

This pass attempts to find instruction chains in one domain and convert them to equivalent instructions in another domain, if it is found profitable.

The patch adds support only for GPR->Mask conversions.
