Moved the _gCRAnnotations declarations to their own object module, which will help to avoid duplicate symbol problems (at least with .a files). Also tweaked things to make it so that the demangler and runtime versions of the message setting code will interoperate (and so that they'll interoperate better with other implementations that might creep in from somewhere, like the one in LLVMSupport). rdar://91095592
