[SCCP] Remove manual folding of terminator instructions. There are two cases handled here: 1) a branch on undef 2) a switch with an undef condition. Both cases are currently handled by ResolvedUndefsIn. If we have a branch on undef, we force its value to false (which is trivially foldable). If we have a switch on undef, we force to the first constant (which is also foldable). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@288725 91177308-0d34-0410-b5e6-96231b3b80d8
