[PATCH] D52674: [AST] Add Obj-C discriminator to MS ABI RTTI

@rnk pointed out on IRC that the MicrosoftCXXNameMangler is actually specifically designed to manage the mangling of only a single name, in which case adding state to it for handling RTTI seems like a natural approach. @rjmccall, what do you think? I think this is much cleaner than having to thread through the RTTI state to every individual method. The ForRTTI_t enum is modeled after the ForDefinition_t enum used in CGM, but I'm happy to switch to a more general struct (as you'd mentioned before) if you prefer.
