[PATCH] D129765: [DAG] SimplifyDemandedBits - don't early-out for multiple use values (WIP)

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon updated this revision to Diff 444685.
RKSimon added a comment.

Fix sad.ll regression - if the multiple-use "all demanded elts" mode failed to find any knownbits, then try again with just the original demanded elts.
