Kill varSetElemsWellScoped in quantifyTyVars
varSetElemsWellScoped introduces unnecessary non-determinism in
inferred type signatures.
Removing this instance required changing the representation of
TcDepVars to use deterministic sets.
This is the last occurence of varSetElemsWellScoped, allowing me to
finally remove it.
Test Plan:
./validate
I will update the expected outputs when commiting, some reordering
of type variables in types is expected.
