Connor Abbott 7f0cd6f153 nir/opt_if: Use early returns in opt_if_merge()

finding the if conditions in the next commit. Refactor this function to
use early returns like our other optimizations, so that this isn't an
issue.

appropriate, you should ask your question on `Freenode's #dri-devel
<irc://chat.freenode.net#dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
