As for 1), I haven't added the testcase because I partially agree with Eric
Botcazou on that scheduling just shouldn't be enabled for -O0, and in that case
the testcase would immediately stop testing this issue. For 2), perhaps, but
not sure what other spots would use that helper, while e.g. one spot in
cfgrtl.c has similar code, it doesn't have the same code, it tests for two bbs,
not just one, and has different behavior based on which one of them it is.
Sure, if you have time and can take over testing this, go ahead.
