There is no BuiltinsRISCV.def and I can't find a way to make it work like BuiltinRISCVVector.def where rvv and sifive builtins can be in separate files (without modifying BuiltinsRISCV.td).  
I have rewrite BuiltinsRISCVXCV.def in the same format as BuiltinsRISCV.td and included it in BuiltinsRISCV.td for now, I'm willing to explore further if there is better solution.
