Richard Smith b4418e29ec Properly check that a constraint appears after is. (#2304)
In particular, if we find the name of an interface after `is`, it should
be exapnded to a constraint, including any implied constraints such as
extended interfaces, rather than forming a constraint requiring only
that interface in isolation.
