Do not pessimize range in set_nonzero_bits.
Currently if we have a range of [0,0] and we set the nonzero bits to
1, the current code pessimizes the range to [0,1] because it assumes
the range is [1,1] plus the possibility of 0. This fixes the
oversight.
gcc/ChangeLog:
* value-range.cc (irange::set_nonzero_bits): Do not pessimize range.
(range_tests_nonzero_bits): New test.
