From CY:

This patch prevent from defining new register class for vsx that uses 64-bit altivec register, it reuses VFRC register class, and does required changes when printing assembly code.

VsxUseAltivecReg and VFRC are used in "PPCInstPrinter::printOperand", "PPCAsmPrinter::printOperand", in order to get correct register name for vsx that uses 64-bit altivec register.
