getCrossCopyRegClass - Returns a legal register class to copy a register in the specified class to or from.
Returns NULL if it is possible to copy between a two registers of the specified class.

getPointerRegClass - Return the register class to use to hold pointers.
This is currently only used by LOAD_STACK_GUARD, which requires a non-r0 register, hence ADDR64.
