Paolo Tranquilli 033b239b22 Swift: collapse TypeRepr hierarchy
Now `TypeRepr` is a final class in the AST, which is more or less just
a type with a location in code.

As the frontend does not provide a direct way to get a type from a
type representation, this information must be provided when fetching
the label of a type repr.

This meant:
* removing the type repr field from `EnumIsCaseExpr`: this is a virtual
  AST node introduced in place of some kinds of `IsEpxr`. The type
  repr is still available from the `ConditionalCheckedCastExpr` wrapped
  by this virtual node, and we will rebuild the original `IsExpr` with
  the IPA layer.
* some logic to get the type of keypath roots has been added to
  `KeyPathExpr`. This was done to keep the `TypeRepr` to `Type` relation
  total in the DB, but goes against the design of a dumb extractor. The
  logic could be moved to QL in the future
* in the control flow library, `TypeRepr` children are now ignored. As
  far as I can tell, there is no runtime evaluation going on in
  `TypeRepr`s, so it does not make much sense to have control flow
  through them.
