[TargetLowering] Add ISD::AND handling to SimplifyDemandedVectorElts If either of the operand elements are zero then we know the result element is going to be zero (even if the other element is undef). Differential Revision: https://reviews.llvm.org/D55558 llvm-svn: 348926

[DAGTypeLegalizer] Handle widening truncate to vector of i1. Previously, PromoteIntRes_TRUNCATE() did not handle the case where the operand needs widening, which resulted in llvm_unreachable(). This patch adds the needed handling, along with a test case. Review: Eli Friedman, Simon Pilgrim. https://reviews.llvm.org/D31077 llvm-svn: 298357
