So the reason for that was an awkward possibility of ending up with 0
compilers. That was because during the argument check in
```CompilerConfig::check_args_consistency()``` We checked for
```Arguments::is_interpreter_only()``` instead of
```CompilerConfig::is_interpreter_only()```. The former doesn't check if
```TieredStopAtLevel=0``` is present. Anyways, I fixed the check and reverted
this change.
