c++: destroy retval on throwing cleanup in try [PR33799]
My earlier attempt to fix this bug didn't handle the case where both the
return and the throwing cleanup are within a try-block that catches and
discards the exception. Fixed by adding the retval cleanup to any
try-blocks as well as the function body. PR102191 pointed out that we also
weren't handling templates properly, so I moved the call out of the parser.
