Make sure we consistently use getParentForLookup() and not getParent() when looking at generic DeclContexts. This is because an extension or protocol that is nested inside of another generic context must never inherit generic parameters from the parent context. We already had this invariant enforced in some places, but now that we do it more consistently we can fix more crashes of this kind. Fixes <rdar://problem/58813746>, <https://bugs.swift.org/browse/SR-13004>.
