RFR: 8341908: CodeHeapAnalytics: Output Imperfections and unwanted vm termination [v3]

[Lutz Schmidt]

> Output is properly aligned again now. Was messed up when method hotness was removed (part of method sweeper).
> Assertions have been replaced by printing an error message and gracefully returning. Avoids vm crashes caused by diagnostic actions.
> Some code restructuring, removal of redundancies.
> 
> Reviews are highly welcomed.
