* tree-ssa-pre.c (bb_value_sets_t): Add antic_safe_loads.
(ANTIC_SAFE_LOADS): New macro.
(find_or_generate_expression): Add prototype.
(set_contains_value): Allow null set for sake of not always having
to allocate ANTIC_SAFE_LOADS.
(phi_translate): Move placement of AGGREGATE_TYPE_P check.
Allow COMPONENT_REF too.
(valid_in_set): Allow COMPONENT_REF.
Check ANTIC_SAFE_LOADS too.
(compute_antic_aux): Print out ANTIC_SAFE_LOADS.
(compute_rvuse_and_antic_safe): Add ANTIC_SAFE computation, and
rename.
(can_PRE_operation): Add COMPONENT_REF.
(create_component_ref_by_pieces): New function.
(create_expression_by_pieces): Use create_component_ref_by_pieces.
(insert_aux): Move AGGREGATE_TYPE_P check here.
(compute_avail): Set bb local stmt uids.
(pass_pre): Use TODO_update_ssa_only_virtuals.
