[PATCH] D66921: GlobalISel: Add known bits to InstructionSelector

[Aditya Nandakumar via Phabricator via llvm-commits]

Hi Matt, this looks reasonable - though when (if) we add a more complex implementation (perhaps precomputes knownbits) we might have to revisit this.
For now, it's close to zero cost. LGTM.
