[13] RFR(T) 8223539: compiler/graalunit/HotspotTest.java hotspot.test.CheckGraalIntrinsics AssertionError: found plugins for intrinsics

[Vladimir Kozlov]

https://bugs.openjdk.java.net/browse/JDK-8223539

8222074 added new Math intrinsics abs(F), abs(I), abs(J).
Usually new intrinsics should be listed in CheckGraalIntrinsics.java Graal's unit test until they 
are implemented in Graal. And it was done in 8222074 changes [1].

But Graal has own intrinsics - plugins. And there already plugins for Math.abs(F) and Math.abs(D) 
[2]. That is why the test failed.

The fix is trivial - remove line with Math.abs(F) from CheckGraalIntrinsics.java:
