Slava Pestov c257cdbc7c Sema: Relax primary associated type matching in matchExistentialTypes() ...

Recently I found a soundness hole here, where we would allow conversion
between `any P<T>` and `any Q<T>` even if P and Q have different primary
associated types.

However, the fix was too strict, because we still want to allow the
conversion when the associated types have the same name.

Fixes rdar://141968103.
