[PATCH] D155472: [DAG] Attempt shl narrowing in SimplifyDemandedBits

[Arthur Eubanks via Phabricator via llvm-commits]

aeubanks added a comment.

a lot of the crashes seem to be on this line <https://github.com/llvm/llvm-project/blob/a8f8613dec435cfb78bf202c392f2acf150a5937/clang/lib/AST/DeclTemplate.cpp#L90>, perhaps that code has UB? could we revert this while investigating?
