[PATCH] D31821: Remove redundant copy in recurrences

[Matthias Braun via Phabricator via llvm-commits]

MatzeB added a comment.

This looks pretty complicated for the task at hand. Wouldn't this be a simpler transformation to perform at a place where we are still in Machine SSA and have use-def information for free and also have phis around to indicate loops so we can do without a MachineLoopInfo instance.
