* tree-if-conv.c (add_to_dst_predicate_list): Use "edge", not
"basic_block" description as its third argument. Update function
calls to get destination bb from "edge" argument. Save "cond" into
aux field of the edge. Update prototype for changed arguments.
(find_phi_replacement_condition): Operate on incoming edges, not
on predecessor blocks. If there is a condition saved in the
incoming edge aux field, AND it with incoming bb predicate.
Return source bb of the first edge.
(clean_predicate_lists): Clean aux field of outgoing node edges.
(tree_if_conversion): Do not initialize cond variable. Move
variable declaration into the loop.
(replace_phi_with_cond_gimple_modify_stmt): Remove unneded
initializations of new_stmt, arg0 and arg1 variables.
