Log:
    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.
