objc_autoreleasePoolPop() can throw if a -dealloc does.
Model it as throwing so that the exception can be caught.
This is generally not expected to have significant code-size
impact because the contents of the @autoreleasepool block
are very likely to contain a call, very likely at the same
cleanup level as the @autoreleasepool itself.
