[PATCH] D83153: [DAGCombiner] Prevent regression in isMulAddWithConstProfitable

[Sam Elliott via Phabricator via llvm-commits]

lenary added a comment.

If it's not too much trouble, I've added D83159 <https://reviews.llvm.org/D83159> as a parent patch, which are the tests for this change in the RISC-V backend.

I realise this shouldn't block changes to the other targets, but given the transform is target-independent, it makes sense to see how it affects more targets if possible.
