            * config/avr/avr.md (mov<mode>) [avr_mem_memx_p]: Expand in such a
            way that the destination does not overlap with any hard register
            clobbered / used by xload8qi_A resp. xload<mode>_A.
            * config/avr/avr.cc (avr_out_xload): Avoid early-clobber
            situation for Z by executing just one load when the output register
            overlaps with Z.
