Inherited designated initializers got the same availability as the corresponding initialier in the superclass. However if the superclass was more available than the subclass, we would generate a diagnostic that a member cannot be more available than its containing type. This diagnostic had an unknown source location, since the location was for a synthesized declaration, causing confusion. Fixes <https://bugs.swift.org/browse/SR-7881> aka <rdar://problem/40853731>.
