CSDiag was misinterpreting the result of checkGenericArguments(). A result of SubstitutionFailure does not mean a diagnostic was emitted, only a result of Failure means that. This fixes a case where we did not emit a diagnostic, result in a crash on invalid. The diagnostic is still poor, but that's better than crashing. Fixes <https://bugs.swift.org/browse/SR-5932>, <rdar://problem/34522739>.
