Jordan Rose 859b31f9c6 [AST] Fix printing of *un*constrained generic extensions ...

We were redundantly printing constraints that were implied by the base
type (the type being extended). Rather than special-casing constraints
on a protocol's 'Self' type, omit any requirements that are already
satisfied by the extended type instead.
