Some personality routines require funclet exit points to be clearly marked, this is done by producing a token at the funclet pad and consuming it at the corresponding ret instruction. CleanupReturnInst already had a spot for this operand but CatchReturnInst did not. Other personality routines don't need to use this which is why it has been made optional. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@245149 91177308-0d34-0410-b5e6-96231b3b80d8
