  -----------
  [flang][OpenMP] fix reduction of arrays with non-default lower bounds (#89611)

It turned out that `hlfir::genVariableBox` didn't add lower bounds to
the boxes it created. Using a shapeshift instead of only a shape adds
the lower bounds information to the thread-local copy of the box.

Fixes #89259
