[PATCH] D44043: [DAGCombine] Remove AND in SETCC if we can prove they are unneeded

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

I was asked not to add DemandedElts to individual cases in computeKnownBits until you have test coverage - this should probably be the same for AnyToZeroExtLoads. That will be easier if you move the AnyToZeroExtLoads arg to the end to make use of the default nullptr.
