It isn't just the case where some unimportant testcase would need to be
xfailed, there are 5% slowdowns on SPEC and similar bugs as well.
Yes, PR101523 is important to get fixed, but we've lived with it for years and
don't have time in GCC 14 cycle to deal with the fallouts from the change,
which there are clearly many.  If the fix was done in stage1, there could be
time to deal with that, but we want to release in 2 weeks or so.
