* final.c (compute_alignments): New function.
(init_insn_lengths): Do not care label_align.
(LABEL_ALIGN_AFTER_BARRIER): Default to 1.
(LABEL_ALIGN_AFTER_BARRIER_MAX_SKIP): Default to 0.
(JUMP_ALIGN, JUMP_ALIGN_MAX_SKIP): New.
(shorted_branches): Realloc label_align array; do
not call init_insn_lengths; Do not care about loop alignments.
* output.h (compute_alignments): Declare.
* toplev.c (rest_of_compilation): Call compute_alignments.
* tm.texi (JUMP_ALIGN, JUMP_ALIGN_MAX_SKIP): Document.
* predict.c (block_info_def): Add npredecesors, remove nvisited;
change visited to tovisit.
(propagate_freq): Use faster traversing algorithm.
(estimate_loops_at_level, estimate_bb_frequencies): Change visited
to tovisit; reverse meaning.
* predict.c (struct block_info_def): Remove nvisited.
(propagate_freq): Use EDGE_DFS_BACK to detect irreducible regions.
(estimate_bb_frequencies): Call mark_dfs_back_edges.
