Compute the discriminant value used by a specific variant. Unlike discriminants, this is (amortized) constant-time, only doing at most one query for evaluating an explicit discriminant (the last one before the requested variant), assuming there are no constant-evaluation errors there.

Returns a list of types such that Self: Sized if and only if that type is Sized, or TyErr if this type is recursive.

Oddly enough, checking that the sized-constraint is Sized is actually more expressive than checking all members: the Sized trait is inductive, so an associated type that references Self would prevent its containing ADT from being Sized.

Due to normalization being eager, this applies even if the associated type is behind a pointer, e.g. issue #31299.
