JDK-8181124 - Get rid of compiler.testlibrary.rtm.predicate
Description
JDK-8181124 replaced usages of compiler.testlibrary.rtm.predicate (which depended on WhiteBox API) w/ @requires, so now compiler/rtm/cli don't use WhiteBox API and can be run w/o it and given the actual testing is done the spawned JVMs by tests, the test code can also be run in driver mode.
Comments
Fix Request (11u) This improves test performance. Patch applies cleanly to 11u, affected tests still pass. tier{1,2,3} (which run some of these tests) pass as well.

In 11u, this patch saves about 10s out of 330s of user time when running "compiler/rtm/cli" tests. A minor improvement, sure, but interesting one nevertheless.
