Hi,
this is (very likely partial) fix for PR92860 where optimize attribute
incorrectly rewrites flag_toplevel_reorder which we handle as global
flag. In fact we support per-symbol toplevel reordering for a while
so we only need to add the annotation. However we need to inspect all
other flags implied by optimize that they have Optimization attribute on
them.
Also i think this should be backoported to release branches, but it
breaks LTO streaming compaibility.
