On SystemZ there are a set of "access registers" that can be copied in and out of 32-bit GPRs with special instructions. These instructions can only perform the copy using low 32-bit parts of the 64-bit GPRs. However, the default register class for 32-bit integers is GRX32, which also contains the high 32-bit part registers. In order to never end up with a case of such a COPY into a high reg, this patch adds a new simple pre-RA pass that selects such COPYs into target instructions. This pass also handles COPYs from CC (Condition Code register), and COPYs to CC can now also be emitted from a high reg in copyPhysReg().
