Shoaib Meenai c69e359857 [ObjCARC] Prevent code motion into a catchswitch ...

A catchswitch must be the only non-phi instruction in its basic block;
attempting to move a retain or release into a catchswitch basic block
will result in invalid IR. Explicitly mark a CFG hazard in this case to
prevent the code motion.
