Duncan Sands 2c47368a7d Fix PR6165. The bug was that LHSKnownZero was being and'd with DemandedMask ... when it should have been and'd with LowBits. Fix that and while there beef up the logic in the case of a negative LHS. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94745 91177308-0d34-0410-b5e6-96231b3b80d8		2010-01-28 17:22:42 +00:00
