re PR middle-end/69546 (wrong code with -O and simple int128 arithmetics)
PR tree-optimization/69546
* wide-int.cc (wi::divmod_internal): For unsigned division
where both operands fit into uhwi, if o1 is 1 and o0 has
msb set, if divident_prec is larger than bits per hwi,
clear another quotient word and return 2 instead of 1.
Similarly for remainder with msb in HWI set, if dividend_prec
is larger than bits per hwi.
* gcc.dg/torture/pr69546.c: New test.
