WRCI can't handle AKD arrays

Extended Description

Created an attachment (id=989)
source code to reproduce fault
The wrci unit test suite now includes wrciOffset.sac and wrciOffsetAKD.sac;
these are intended to show array reuse on AKS and AKD arrays, respectively.
WRCI does not support AKD arrays, which really sucks.
Here's an example of AKD code, where a reference with offset (to
another partition) to the reuse candidate array could work, but does
not. 
   AAA = _reshape_VxA_( id( [ 25, 10]), iota( id( 250)));
   gw = shape( AAA) - [ 15, 0]; // AKA [10 10]
   AAA = with {
          ([0,0] <= iv < gw): AAA[iv + [ 10, 0]] + 1000;
         } : modarray(AAA);
I intend to move IVEXC after WRCI, and then "should" be able to
extend WRCI/RWO to do the job.
