m68k.c (post_inc_operand,pre_dec_operand): New.

        * config/m68k/m68k.c (post_inc_operand,pre_dec_operand): New.
        * config/m68k/m68k.h (PREDICATE_CODES): add post_inc_operand,
        pre_dec_operand.
        * config/m68k/m68k.md (zero_extend*2): delay the splitting of the
        pattern until reload is finished to allow better code generation
        and split them completely into separate instrunctions.
        (*andsi3_split): New pattern.
