JDK-8146549 - Move TestMutuallyExclusivePlatformPredicates and TestPlatformIsTieredSupported to test/lib-test
Description
At the moment several existing tests as well as some tests on segmented code cache that will be added soon check VM mode by looking at the "java.vm.info" content.

Following methods should be added to com.oracle.java.testlibrary.Platform to simplify task of VM's mode checking:

isComp()
isMixed()
isInt()
