* 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.
* i386.c (ix86_agi_depdendant): Lea causes AGI only on the Pentium
(ix86_adjust_cost): Teach scheduler that latency to load operand can
be masked.
