Refactor on the road to #5027 -- remove unused Scope#strinterp

One of the uses of lookupvar was in the method Scope#strinterp; this method
is no longer used (string interpolation is now handled by the parser (for
the syntax) and AST nodes (for the semantics)) so this use of lookupvar can
be excised, along with a fair amount of surrounding code.
