Jeff Young 8054f1a948 Apply a more sophisticated test for ignoring isInCoupledDiffPair. 
The basic problem is that the DRC engine does length testing and skew
testing by collecting all the diff pair constituent parts and pairing them
itself.  Since each part is collected on its own, we need to ignore the
'B' unit when evaluating any conditional expressions.  However, doing this
in general means that when evaluating "OwnClearance()" we also ignore the
'B' unit and return the diff pair CLEARANCE_CONSTRAINT when we shouldn't.

This implements a more discerning test which know what the current requested
constraint is when evaluating expressions.
