RFR(XXS): 8034775: Failing to initialize VM when running with negative value for -XX:CICompilerCount

[Igor Ignatyev]

Albert,

your test fails, if it runs on VM w/o Tiered.
I'd recommend to add -XX:-TieredCompilation as an arg:
>   34     ProcessBuilder pb = ProcessTools.createJavaProcessBuilder("-XX:-TieredCompilation -XX:CICompilerCount=-1");
and change the check:
>   37     String expectedOutput = "CICompilerCount of -1 is invalid; must be at least 1";
