re PR middle-end/54364 (Tail call jumps not threaded)
PR middle-end/54364
* bb-reorder.c (connect_better_edge_p): New added.
(find_traces_1_round): When optimizing for size, ignore edge frequency
and probability, and handle all in one round.
(bb_to_key): Use bb->index as key when optimizing for size.
(better_edge_p): The bb with smaller index is better when optimizing
for size.
(connect_traces): When optimizing for size, connect block n with
block n + 1; connect trace m with trace m + 1 if falling through.
(gate_handle_reorder_blocks): Enable bbro when optimizing for -Os.
