[PATCH] D49303: [CodeGen][ObjC] Treat non-escaping blocks as global blocks to make copy/dispose a no-op

Fix a bug where the capture cleanups weren't pushed when BlockDecl::doesNotEscape() returns true.

Test that, when ARC is enabled, captures are retained and copied into the stack block object and destroyed when the stack block object goes out of scope.
