RFR: 8266088: compiler/arguments/TestPrintOptoAssemblyLineNumbers test should user driver mode [v2]

[Igor Ignatyev]

> Hi all,
> 
> could you please review this tiny patch for `TestPrintOptoAssemblyLineNumbers` test? 
> from JBS:
>> compiler/arguments/TestPrintOptoAssemblyLineNumbers class is a driver class that spawns a new JVM and validates its output, there is no need for the JVM which executes TestPrintOptoAssemblyLineNumbers to be run w/ all vm flags.
> 
> besides addressing this, the patch also removes `/compiler/patches` from `@library` as it's not needed and fixes code style here and there.
> 
> testing:
> - [x] `compiler/arguments/TestPrintOptoAssemblyLineNumbers` on `{linux,windows,macosx}-x64-debug`
> 
> Thanks,
> -- Igor
