[PATCH] D101423: [InstCombine] Fold overflow bit of [u|s]mul.with.overflow in a poison-safe way

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

I have a really 'are you nuts' proposal.
How about we canonicalize all i1 and/or's into `select` form?
Then that instsimplify code becomes dead, and we can simply port it here.
And we'll weed out all the remaining patterns that still only handle the and/or forms/
