Use the reserved spelling for the weak attribute. Move the definition into an implementation file to avoid multiple definitions of the function from being emitted. PE/COFF does not support weak symbols, however, the runtime will never link against LLVMSupport, so provide a single, strong definition of the function. Mark it as hidden visibility so that we do not expose it outside of the runtime.
