Many have the offending PR already identified, so skip those. The others will 
often say "worked in DMD x.xx and fails with DMD y.yy" where x.xx < y.yy.

The idea is then to use digger to determine which change caused the failure:

   https://github.com/CyberShadow/Digger

Just pick any where success/failure is pretty clear and the failing example is 
clear.

Even doing just one will be useful.

Thanks!
