Patryk Wychowaniec 5650688e72 [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
https://github.com/rust-lang/rust/issues/98167
