* basic-block.h (struct edge_def): Remove crossing_edge.
(EDGE_CROSSING): New define.
(EDGE_ALL_FLAGS): Update.
* bb-reorder.c (find_traces_1_round, better_edge_p,
find_rarely_executed_basic_blocks_and_cr, fix_up_fall_thru_edges,
find_jump_block, fix_crossing_conditional_branches,
fix_crossing_unconditional_branches, add_reg_crossing_jump_notes):
Replace all occurences of crossing_edge with an edge flag check
or set/reset.
* cfgcleanup.c (try_simplify_condjump, try_forward_edges,
try_crossjump_bb): Likewise.
* cfglayout.c (fixup_reorder_chain): Likewise.
* cfgrtl.c (force_nonfallthru_and_redirect,
commit_one_edge_insertion): Likewise.
* Makefile.in (cfganal.o): Depend on TIMEVAR_H.
* tree-flow.h (compute_dominance_frontiers): Move prototype...
* basic-block.h: ...here.
* tree-cfg.c (compute_dominance_frontiers_1,
compute_dominance_frontiers): Move from here...
* cfganal.c: ...to here. Include timevar.h.
