RFR(M) : Add CTW test for boot module

[Vladimir Kozlov]

Igor,

When we ran CTW in Nightly before we sliced rt.jar to few parts using CompileTheWorldStartAt/CompileTheWorldStopAt to 
get better parallelism.
Can we do the same here? You already have mechanism to restart with N+1 after error.
2 hours for serial test execution is too long - would be nice to parallelize it.

Thanks,
Vladimir

The test takes approx. 2 hours to complete.
