[Serializer] canonicalization of GenericSignature. The second type of WitnessMarker for deserialized GenericSignature is null. But the second type for parsed GenericSignature is not null, causing type mismatch error when linking a SILFunction. This commit ignores the second type of WitnessMarker when profiling the GenericSignature. rdar://17998988 Swift SVN r21178
