Upgrade UniqSet to a newtype
The fundamental problem with `type UniqSet = UniqFM` is that `UniqSet`
has a key invariant `UniqFM` does not. For example, `fmap` over
`UniqSet` will generally produce nonsense.
* Upgrade `UniqSet` from a type synonym to a newtype.
* Remove unused and shady `extendVarSet_C` and `addOneToUniqSet_C`.
* Use cached unique in `tyConsOfType` by replacing
`unitNameEnv (tyConName tc) tc` with `unitUniqSet tc`.
