Extended Description

After roughly Build #16606:16607:MODIFIED, we get the following code in
AWLF:
  v = [scalar];
  zero = [0];
  s2 = sel( zero, v);
  _sub_SxS_( s2, scalar);
This is with:
 sac2c prdAKD.sac -v1 -nowlf -doawlf -extrema -b11:ebt >crud
in sac/testsuite/optimizations/awlf
This, in turn, cripples AWLFI.
SCCF should replace s2 by scalar, but it's not doing it.
