I'm not sure if this is a good idea to move it to debug-scopes.h, but now we
need scopes locations along with ScopeInfo. Looks like, to push location into
ScopeInfo isn't good way to go: it is especially compressed, while locations are
needed only by debugger.
I would be glad to hear better options.

ExtendedScopeInfo sgtm.
