cpMem2RegMI - Generate SparcV9 MachineInstrs to load a register (DestReg) from memory, at [PtrReg + Offset]. Register numbers must be the unified register numbers. RegType must be the SparcV9 register type of DestReg. When DestReg is ccr, scratchReg must be the number of a free integer register. The newly-generated MachineInstrs are appended to mvec.
