* tree-ssa-structalias.c (equiv_class_add)
(perform_var_substitution, free_var_substitution_info): Created a
new equiv_class_pool allocator pool for struct
equiv_class_label. Changed the pointer_equiv_class_table and
location_equiv_class_table hash tables to not iterate freeing all
elements in the end, but just free the pool.
