* tree-ssa-dom.c (struct edge_info): New structure holding
edge equivalences and edge redirection information.
(get_eq_expr_value, record_dominating_conditions): Kill.
(propagate_to_outgoing_edges): Renamed from cprop_into_phis.
Call record_edge_info.
(allocate_edge_info, free_edge_info): New.
(tree_ssa_dominator_optimize): Use propagate_to_outgoing_edges
rather than cprop_into_phis. Free all edge infos before threading
jumps.
(thread_across_edge): Allocate new edge info structures as needed
and store the redirection target into the edge info structure
instead of the edge's AUX field.
(dom_opt_initialize_block): Mark unused argument with ATTRIBUTE_UNUSED.
(record_equivalence_from_incoming_edge): Lose unnecessary argument.
Revamp code which finds and records equivalences associated with
edges to use saved data in the edge_info structure.
(record_equivalencs_from_phis): Similarly.
(dom_opt_finalize_block): Revamp code which finds and records
equivalences associated with edges to use saved data in the
edge_info structure.
(build_and_record_new_cond): New function.
(record_conditions): Use build_and_record_new_cond to record
dominating conditions.
(record_edge_info): New function.
(record_range): Tighten test for conditions which create
useful range records.
