[PATCH] D124839: [DAG] Enable ISD::SHL SimplifyMultipleUseDemandedBits handling

[Jay Foad via Phabricator via llvm-commits]

foad added a comment.

I'm confused because the description says SimplifyMultipleUseDemandedBits but the patch changes SimplifyDemandedBits and I don't know how they relate.

Having said that, the actual patch makes sense to me and the AMDGPU changes are fine and save a few instructions overall.
