[PATCH] D151099: [InstCombine] Remove computeKnownBits() fold for returns

[Noah Goldstein via Phabricator via llvm-commits]

goldstein.w.n added a comment.

This seems a bit counter-intuitive to the aim InstCombine, which unless I'm mistaken
is to simplify/cannonicalize IR to help other passes.
I would certainly think a constant is easier to work with than whatever expression
it came from.
