`java/lang/invoke/VarHandles` tests run with C1, C2 and tiered compilations and the test cases are executed in the warm up loop with 20000 iterations to verify C1, C2 intrinsics. Default Tier4CompileThreshold is 15000.
This PR proposes to scale the compile threshold to 0.1 such that the warm up loop can be reduced to 2000 iterations. This will speed up the test execution time.
