So for the attached testcase, we assumed that zero_one_valued_p would be the value [0,1] but currently zero_one_valued_p matches also signed 1 bit integers. This changes that not to match that and fixes the 2 new testcases at all optimization levels. OK for GCC 13? Bootstrapped and tested on x86_64-linux-gnu with no regressions.
