RFR(S): 8008211 : Some of WB tests on compiler fails

[Igor Ignatyev]

There are two different reasons for this failure:

    1. with '-Xcomp':
CompilerWhiteBoxTest#method() is inlined into #compile() on first 
invocation of #test(). so 'WHITE_BOX.setDontInlineMethod(METHOD, true)' 
does nothing; #method() isn't compiled;

    2. with '-XX:+TieredCompilation' and certain relation between 
'CompileThreshold' and 'Tier*' values (e.g. -XX:CompileThreshold=100 and 
default Tier* values):
since 'CompileThreshold' doesn't use in Tiered as threshold, but uses in 
tests we have situation in which CompilerWhiteBoxTest#compile() invokes 
#method() insufficient time for compilation;

Best regards,
Igor Ignatyev
