  Log Message:
  -----------
  [LV] Do not check widening decision for instrs outside of loop.

No widening decisions will be computed for instructions outside the
loop. Do not try to get a widening decision. The load/store will be just
a scalar load, so treating at as normal should be fine I think.

Fixes PR46950.
