* config/h8300/h8300.c: (h8300_push_pop): Use bool type for
        boolean parameters.  Use emit_jump_insn when emitting a pop
        instruction containing a return insn.
        (push): Use 'true' rather than '1' as second parameter to F.
        (h8300_expand_prologue): Likewise.
        Use 'true' and 'false' for boolean parameters to
        h8300_push_pop.
        (h8300_expand_epilogue): Likewise.
