Extended Description

Created an attachment (id=987)
source code to reproduce fault
_pinl_2868__flat_33 = _add_SxS_( N__SSA0_1, -1);
  _wlsimp_17660 = _sub_SxS_( N__SSA0_1, _pinl_2868__flat_33);
This code is generated by WLSIMP, leaving a GENWIDTH value 
with a non-constant value, although the value is actually the constant 1.
I'm not sure if this affects anything downstream, but if so,
some additional traversals are called for after WLSIMP.
Here's how to reproduce it in Build #18310.
