[8u] RFR(S): 8247817: Some incompatible APIs in jdk/test/lib

[Hohensee, Paul]

Would you describe the problems you encountered that this patch solves please? The Whitebox issue is obvious, but the purpose of the other changes isn't.

Thanks,
Paul

    Hi, maintainers,

    Could you review this webrev for jdk8u-dev/jdk?

    Description:

    I ran into these problems when I try to use jdk/test/lib of jdk repo,  
    which was introduced for JFR testing,  to run hotspot/test/vmtestbase.

    I guess the JFR testing doesn't cover them. IMHO, we'd better fix them 
    for jdk8u, Otherwise we will observe something strange when we really 
    use them.

    eg. The whitebox api isMethodCompilable doesn't work. It's because 
    CompLevel_any=-1 in jdk8u. Whitebox APIs must be consistent with the 
    implementation of hotspot.

    thanks,
