We already handled all of the new tests identically, but several of those went through a lot of unnecessary processing before getting folded. Another motivation for grouping these cases together is that InstCombine needs a similar fold. Currently, it handles the 'not' cases inefficiently which can lead to bugs as described in the post-commit comments of: https://reviews.llvm.org/D32143 llvm-svn: 303295
