Emits a call to __cxa_begin_catch and enters a cleanup to call __cxa_end_catch.
If -fassume-nothrow-exception-dtor is specified, we assume that the exception object's dtor is nothrow, therefore the __cxa_end_catch call can be marked as nounwind even if EndMightThrow is true.
EndMightThrow | - true if __cxa_end_catch might throw |
