re PR tree-optimization/93098 (ICE with negative shifter)

PR tree-optimization/93098
* match.pd (popcount): For shift amounts, use integer_onep
or wi::to_widest () == cst instead of tree_to_uhwi () == cst
tests.  Make sure that precision is power of two larger than or equal
to 16.  Ensure shift is never negative.  Use HOST_WIDE_INT_UC macro
instead of ULL suffixed constants.  Formatting fixes.

* gcc.c-torture/compile/pr93098.c: New test.
