- debug insn, for this would get n_useless_values out of sync, but we
- want increment it if all locs in the list that were ever referenced
- in nondebug insns are removed from the list.
-
- In the general case, once we do that, we'd have to stop accepting
- nondebug expressions in the loc list, to avoid having two values
- equivalent that, without debug insns, would have been made into
- separate values. However, because debug insns never introduce
- equivalences themselves (no assignments), the only means for
- growing loc lists is through nondebug assignments. If the locs
- also happen to be referenced in debug insns, it will work just fine.
-
- A consequence of this is that there's at most one debug-only loc in
- each loc list. If we keep it in the first entry, testing whether
- we have a debug-only loc list takes O(1).
-
- Furthermore, since any additional entry in a loc list containing a
- debug loc would have to come from an assignment (nondebug) that
- references both the initial debug loc and the newly-equivalent loc,
- the initial debug loc would be promoted to a nondebug loc, and the
- loc list would not contain debug locs any more.
-
- So the only case we have to be careful with in order to keep
- n_useless_values in sync between debug and nondebug compilations is
- to avoid incrementing n_useless_values when removing the single loc
- from a value that turns out to not appear outside debug values. We
- increment n_useless_debug_values instead, and leave such values
- alone until, for other reasons, we garbage-collect useless
