[ThinLTO] Make ValueInfo operator!= consistent with operator== (NFC)

Compare Ref pointers instead of GUID, to handle comparison with special
empty/tombstone ValueInfo. This was already done for operator==, to
support inserting ValueInfo into DenseMap, but I need the operator!=
side change for upcoming AsmParser summary parsing support.
