[AVR] Fix expanding MOVW for overlapping registers
When expanding a MOVW (16-bit copy) to two MOVs (8-bit copy), the
lower byte always comes first. This is incorrect for corner cases like
'$r24r23 -> $r25r24', in which the higher byte copy should come first.
Current patch fixes that bug as recorded at
