Hi,

I'm seeing a crash

  13:07:13 llc: ../lib/CodeGen/SelectionDAG/TargetLowering.cpp:1878: bool llvm::TargetLowering::SimplifyDemandedBits(llvm::SDValue, const llvm::APInt &, const llvm::APInt &, llvm::KnownBits &, llvm::TargetLowering::TargetLoweringOpt &, unsigned int, bool) const: Assertion `!Known.hasConflict() && "Bits known to be one AND zero?"' failed.

with this patch. I'll see if I can extract a reproducer.
