getContextSubstitutionMap() didn't handle the case where getAnyNominal() returns a ProtocolDecl. This should not take the "fast path", which is only suitable for concrete nominals. This manifested as a crash-on-invalid -- the user probably meant to write "T.Value: Collection" rather than "T.Value == Collection". Fixes rdar://151479861.
