Hi all,

could you please review this small and trivial patch which adds @requires to exclude Level2RecompilationTest, OSRFailureLevel4Test, and TestTypeProfiling tests from execution w/ non default values of TieredStopAtLevel?
the tests expect to have tiered compilation enabled and level 4 compiler available, so they can't be run w/ TieredStopAtLevel < 4.

JBS: https://bugs.openjdk.java.net/browse/JDK-8226795
testing: verified that changed tests are run w/o TieredStopAtLevel, w/ TieredStopAtLevel=4 and aren't run w/ TieredStopAtLevel != 4

Thanks,
-- Igor
