> 
>  *) Reformat Shenandoah tests: that's IDEA fixing indentation and code style, some of dubious
> automatic changes reverted by hand;
>  *) Remove obsolete and ignored TestHeapAlloc;
>  *) Move tests to proper locations: basically eliminating "acceptance" folder, and moving specific
> tests to subfolders, as appropriate;
>  *) Drop "Shenandoah" from test names: make them consistently named
>  *) Prefix tests with "Test", as seems to be the convention
