Strengthen state tracking in const-prop Some/many of the changes are replicated between both the const-prop lint and the const-prop optimization. Behaviour changes: - const-prop opt does not give a span to propagated values. This was useless as that span's primary purpose is to diagnose evaluation failure in codegen. - we remove the `OnlyPropagateInto` mode. It was only used for function arguments, which are better modeled by a write before entry. - the tracking of assignments and discriminants make clearer that we do nothing in `NoPropagation` mode or on indirect places. |
