Instead, introduce a new hasDependentMember() recursive property. The only place that cares about this is associated type inference, where I changed all existing hasTypeParameter() checks to instead check (hasTypeParameter() || hasDependentMember()). We could probably refine this over time and remove some of the hasTypeParameter() checks, but I'm being conservative for now. Fixes <https://bugs.swift.org/browse/SR-4575> and <rdar://problem/31603113>.
