take into consideration that the result of an invoke is only valid in the normal dest, not the unwind dest. This caused 'PHINode::hasConstantValue' to return true in an invalid situation, causing mem2reg to delete a phi that was actually needed. This caused a crash building 483.xalancbmk. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82491 91177308-0d34-0410-b5e6-96231b3b80d8
