I wanted to know exactly what compilers I am testing.

Didn't know about that one. It fills a good purpose but it should not 
guess what compiler levels are available - rather query the VM directly. 
We should also move a lot of useful constants from CompilerWhiteBoxTest 
to CompilerUtils.

I only test the compilers that I know will support this flag. We would 
need some additional test utils for querying what compiler uses the 
JVMCI interface.

Thanks for taking a look,
