36db90d3dd Fix query plans created by whereShortCut() so that they always check 
transitive constraints that drive an index.  The is analogous to the
[f1f9b5de3c59489b] check-in, just for whereShortCut() rather than the
full query planner. Fix for the issue described by
[forum:/forumpost/a65cacbf5e1c41ba|forum post a65cacbf5e1c41ba].

67656ac78a When applying the optimization that disables WHERE clause terms that drive 
indexes, make sure not to do so if the term being disabled is a transitive
constraint.  Fix for the problem identified by
[forum:forumpost/eb8613976a|forum post eb8613976a].

63db0392ae Avoid unnecessary collating sequence and affinity restrictions on the use 
of transitivity.  Add test cases to show that the restrictions are not 
needed.
