 Don't do binder-swap for GlobalIds

 This patch disables the binder-swap transformation in the
 (relatively rare) case when the scrutinee is a GlobalId.
 Reason: we are getting Lint errors so that GHC doesn't
 even validate.  Trac #16346.

 This is NOT the final solution -- it's just a stop-gap
 to get us running again.

 The final solution is in Trac #16296
