[PATCH] D36704: [CodeGen] Improve the consistency of instruction fusion

[Matthias Braun via Phabricator via llvm-commits]

MatzeB added a comment.

You can push this if you want, but I still think that first too loops in fuseInstructionPair() are a poor mans version of the reachability check I outlined in the comments (which would catch more cases).
