Log:
    PR target/54963
    * config/sh/iterators.md (SIDI): New mode iterator.
    * config/sh/sh.md (negdi2): Use parallel around operation and T_REG
    clobber in expander.
    (*negdi2): Mark output operand as early clobbered.  Add T_REG clobber.
    Split after reload.  Simplify split code.
    (abssi2, absdi2): Fold expanders into abs<mode>2.
    (*abssi2, *absdi2): Fold into *abs<mode>2 insn_and_split.  Split insns
    before reload.
    (*negabssi2, *negabsdi2): Fold into *negabs<mode>2.  Add T_REG clobber.
    Split insns before reload.
    (negsi_cond): Reformat.  Use emit_move_insn instead of
    gen_movesi.
    (negdi_cond): Reformat.  Use emit_move_insn instead of a pair
    of gen_movsi.  Split insn before reload.
