Basically, we have this expression in a LOOPFUN:
  
  ZZ = ZZ + ( scalar * BBB);
It should be AWLF'd, but that does not happen, because the
GENARRAY_SHAPEs do not match. We have, between them, essentially this:
_pinl_284__wlbsc_186_sc_e = _idx_sel_( _wlbsc_409_sc_e, shape(BBB));
shapeZZnew = [ _pinl_284__wlbsc_186_sc_e ];
This is a case for IVUTarrayFromProxySel. It will have to appear
in AWLF, but should also appear in LACS and WLPROP, because 
the effect of the above is to make loop-independent variables
look to be loop-dependent, because ID_AVIS(shapeZZnew) !- ID_AVIS(shape(BBB)).
