   4         * match.pd (popcount): For shift amounts, use integer_onep
   5         or wi::to_widest () == cst instead of tree_to_uhwi () == cst
   6         tests.  Make sure that precision is power of two larger than or equal
   7         to 16.  Ensure shift is never negative.  Use HOST_WIDE_INT_UC macro
   8         instead of ULL suffixed constants.  Formatting fixes.
