[PATCH] D107552: [InstCombine] Combine lshr of add that intends to get the carry as llvm.uadd.with.overflow

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

Most of non-correctness bailouts here don't really make sense to me.
Presumably, if it is profitable for a particular backend, said backend should be expanding whatever "bad" intrinsics into it's original form.
