Shorter testcase, compilable and to the point.  We are not able to CSE
the b1 && ... && b8 sequence because we produce control-flow for it
during gimplification.

void bar (short *array,
          short b1, short b2, short b3, short b4,
          short b5, short b6, short b7, short b8)
{
  array[0] = b1 && b2 && b3 && b4 && b5 && b6 && b7 && b8;
  array[1] = b1 && b2 && b3 && b4 && b5 && b6 && b7 && b8;
}
