    PR target/54089
    * config/sh/predicates.md (shift_count_operand): Handle not-SHMEDIA
    case.
    (p27_shift_count_operand, not_p27_shift_count_operand): New predicates.
    * config/sh/sh.md (ashlsi3): Remove parallel and T_REG clobber
    from expander.  Do not emit shift insn for not-SHMEDIA case.

    (ashlsi3_k, ashlsi3_d): ... these new insns.
    * config/sh/sh.c (gen_ashift): Make static.  Add sanity checks.
    Emit ashlsi3_k insn instead of ashlsi3_std in ASHIFT case.
    (gen_ashift_hi): Make static.
    * config/sh/sh-protos.h (gen_ashift, gen_ashift_hi): Remove forward
