m68k.md (subreghi1ashrdi_const32, [...]): Fix SUBREG_BYTE offset.

        * config/m68k/m68k.md (subreghi1ashrdi_const32, bsetmemqi,
        bsetmemqi+1, strict_low_part peephole): Fix SUBREG_BYTE offset.
        (pushqi1): New.
        (adddi_dilshr32, adddi_dishl32): Only data register can be
        source for mem destination.
