When optimizing retain-release-sequences we insert (and delete) ObjC runtime calls. These calls need a funclet operand bundle that refers to the enclosing funclet pad whenever they are inserted in a WinEH funclet. WinEH funclets can contain multiple basic blocks. In order to find the enclosing funclet pad, we have to calculate the funclet coloring first.
