tree-optimize.c (exercute_free_datastructures): Do not disband implicit edges...
* tree-optimize.c (exercute_free_datastructures):
Do not disband implicit edges; do not attempt to build insn list;
do not free cfg annotations.
(execute_free_cfg_annotations); Disband implicit edges here;
free cfg annotations here too.
(pass_free_cfg_annotations); New pass.
(init_tree_optimization_passes); Add pass_free_cfg_annotations.
* tree-ssa-operands.c (free_ssa_operands); Recover; export.
* tree-ssa-operands.h (free_ssa_operands); declare.
* tree-ssa.c (delete_tree_ssa); Free SSA operand; mark stmt modified;
kill PHI nodes.
* tree-ssanames.c (release_defs): Kill addresses_taken.
