Fix tree_simple_nonnegative_warnv_p for VECTOR_TYPEs
tree_simple_nonnegative_warnv_p ends up being called on VECTOR_TYPEs
which I think even gets the wrong answer here for tcc_comparison
since vector bools are signed. The following properly guards
that with !VECTOR_TYPE_P.
* fold-const.cc (tree_simple_nonnegative_warnv_p): Guard
the truth_value_p case with !VECTOR_TYPE_P.
