[PATCH] D39845: [TableGen] Give the option of tolerating duplicate register names

I think that leaving the returned value unspecified is better, at least for now.  Otherwise, we'd need to invent a way to identify the "preferred" register, and then it would need to be preserved by any future modifications to the MatchRegisterName et.al. functions.
