flow.c (mark_set_1): New arguments code and flags; update all callers.

        * flow.c (mark_set_1): New arguments code and flags; update all
        callers.  Track regno_first and regno_last; do HARD_REGNO_NREGS
        test in one place.  Tidy flags tests.  Don't bias REG_N_REFS by
        loop_depth when optimizing for size.  Do new_dead update after
        emitting REG_UNUSED notes.  Merge mark_set_reg code.
        (mark_set_reg): Remove.
        (propagate_one_insn): Use mark_set_1 for call-clobbered registers;
        arrange to not emit REG_UNUSED notes.
