Shorter testcase:
int
foo (bool x, int y)
{
  if (y < 10 && (x ? true : throw 1))
    y++;
  return y;
}

ICE started between r112000 and r113000, before that it failed to compile with
error: void value not ignored as it ought to be error.
The ICE is during gimple_boolify, throw has void_type_node and fold_convert to
boolean_type_node ICEs.
