[PATCH] D146121: [DAG] Move lshr narrowing from visitANDLike to SimplifyDemandedBits

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

I agree - a great deal of folds are poorly designed - we hit a lot of this with D127115 <https://reviews.llvm.org/D127115> and are now seeing very similar things with D152928 <https://reviews.llvm.org/D152928> - if you find examples, PLEASE write up an issue ticket as it speeds up triage a great deal.
