Sanjay Patel 85745f9561 [DAG] optimize negation of bool ... Use mask and negate for legalization of i1 source type with SIGN_EXTEND_INREG. With the mask, this should be no worse than 2 shifts. The mask can be eliminated in some cases, so that should be better than 2 shifts. This change exposed some missing folds related to negation: https://reviews.llvm.org/rL284239 https://reviews.llvm.org/rL284395 There may be others, so please let me know if you see any regressions.
