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. rdar://13660038 llvm-svn: 179630
