+           if (Ty->isFloatTy())

----------------
Using isFloatTy() like this isn't going to be accurate.  If you want to correctly compute the registers used for a call, you really should just use the result of analyzeCallOperands() from isel.  Maybe compute it in isel, then save the result in AArch64FunctionInfo.
