SI-7872 Plug a variance exploit in refinement types
Refinement types are collapsed to a TypeTree with an original
during type checking; this was enough to evade variance validation
in refchecks.
This commit:
- validates the original of `TypeTree`s in refchecks
- changes VarianceValidator to recurse into:
- the originals of `TypeTree`s
- `TypTree` (to cover, e.g. `CompoundTypeTree` / `SelectFromTypeTree`)
It also finds an unreported variance violation in an existing
test case, variances.scala. This looks to be legitimate.
