please review the following patch:
TestArrayCopyNoInitDeopt and TestExplicitRangeChecks fail with -XX:TieredStopAtLevel=1 because they expect methods to be compiled with C2. I added the corresponding checks to the tests.
TieredLevelsTest causes the VM to crash with assert "heap is null" in CodeCache::allocate() because a compilation at level 2 is triggered via the Whitebox API and the corresponding code heap for profiled nmethods is not available with -XX:TieredStopAtLevel=2. I added a check to WhiteBox::compile_method() and also added an assert to CompileBroker::compile_method() to get a more meaningful error message.
Tested with RBT (running).
