Basic support for named constraints as described in [the generics design](https://github.com/carbon-language/carbon-lang/blob/trunk/docs/design/generics/details.md#named-constraints). Support is provided for `extends` and `impl` declarations in `constraint`, but not yet for member aliases. The missing prelude named constraints `Add`, `Mul`, `Ordered`, etc. are also added.
