----------------
we can avoid creating `.debug_loc` list by introducing new `DbgEntity`, e.g. called `DbgScopedVariable` which is handled in a special way (by always creating a single location for it)? Or to set `isSafeForSingleLocation`  (from `DwarfDebug::buildLocationList`) to true if `ScopeBeginSym != nullptr`?
