[PATCH] D64354: [AArch64][GlobalISel] Optimize conditional branches followed by unconditional branches

[Amara Emerson via Phabricator via llvm-commits]

aemerson added a comment.

This seemed a little presumptive to do for all targets for me. I can try to move it earlier into a Combiner helper, since I don't want to put optimizations into the IRTranslator unless we can't do it in other places.

In this case I'm just inverting the condition code, we shouldn't need to insert extra instructions.
