re PR target/50751 (SH Target: Displacement addressing does not work for QImode and HImode)

	PR target/50751
	* config/sh/sh.c (sh_find_mov_disp_adjust): Take machine_mode as the
	first argument instead of mode size.  Move displacement calculations
	to ...
	(mov_insn_size, max_mov_insn_displacement, mov_insn_alignment_mask): 
	... these new functions.
	(disp_adjust): Remove max_mov_disp field.
	(sh_legitimate_index_p): Use max_mov_insn_displacement and
	mov_insn_alignment_mask.
	(sh_address_cost): Use max_mov_insn_displacement.
