89a829b8c7 Constraints for generics (generics details 3) (#818 )

This proposal describes `where` clauses that can add constraints on a type-of-type, for example define restrictions on its associated types. Example:

```
fn FindFirstPrime[T:! Container where .Element = i32]
    (c: T) -> Optional(i32) {
  // The elements of `c` have type `T.Element`, which is `i32`.
  ...
}

fn PrintContainer[T:! Container where .Element is Printable](c: T) {
  // The type of the elements of `c` is not known, but we do know
  // that type satisfies the `Printable` interface.
  ...
}
```

Some other constraints, such as `Sized` are defined as type-of-types directly, possibly parameterized.
