Kotlin code for Objective-C interop is always included to stdlib.
It depends on some C++ code. The latter is compiled conditionally -
only for targets supporting Objective-C interop. That might cause
undefined symbols problems when DCE is not enabled.
To deal with it, we usually have trivial stubs in C++ code, used
for targets not supporting Objective-C interop.
This commit adds a couple of such missing stubs.
