RFR(XS) : 8038240 : new WB API to get nmethod

[Igor Ignatyev]

Vladimir/Morris,

Thanks for review, I've added a nmethod structure w/ code's array and 
compilation level. Since to use NMethod class directly in WhiteBox 
class, class should be added to bootclasspath, I decided to return the 
structure as an object array instead.

I've replaced getMethodCompilationLevel in CompilerWhiteBoxTest and 
planning to remove this method completely in a separate CR.

Also I've removed CLEAR_PENDING_EXCEPTION from CHECK_JNI_EXCEPTION macros
