[PATCH] D31724: [SelectionDAG] Remove special call to LHS computeKnownBits for ANDs with constant RHS.

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

It's producing more test changes now on X86 and other targets. It's producing several regressions in the combine-sdiv.ll test by failing to delete some and instructions. The other X86 changes look pretty neutral. I haven't looked at the other targets yet.
