tree-outof-ssa.c (_elim_graph): Change the type of nodes and const_copies to VEC(tree,heap)*.
* tree-outof-ssa.c (_elim_graph): Change the type of nodes and
const_copies to VEC(tree,heap)*.
(new_elim_graph, delete_elim_graph, elim_graph_size,
elim_graph_add_node, eliminate_build, eliminate_phi): Use VEC
instead of VARRAY.
