This patch will address using the `xscpsgndp` instruction to copy floating point scalar registers instead of the `xxlor` (specifically `XXLORf`) instruction that is currently used on https://reviews.llvm.org/P9. It includes:

- The change in instruction opcode to utilize `xscpsgndp` instead of `xxlor` when copying the floating point scalar registers
- An update of test cases to reflect this behaviour
- An update to test cases to include the `-ppc-vsr-nums-as-vr -ppc-asm-full-reg-names` `llc` options
