CF_OPTIONS is defined differently in the SDK based on a __cplusplus preprocessor branch. As a result, declarations referencing CF_OPTIONS are mangled differently depending on if C++ interop is enabled. This meant a module compiled with cxx interop on could not be linked with a module compiled without and vice versa. This patch modifies the mangler such that the mangled names are consistent. This is achieved by feeding the mangler a modified AST node that looks like the Objective-C definition of CF_OPTIONS, even when we have cxx interop enabled.
