Hi all,

could you please review this small and trivial patch which cleans up hotspot problem lists?

 - 8224234 : "compiler/codegen/TestCharVect2.java fails in test_mulc" was fixed recently w/o removing problem list entry
 - 8221577 : "[Graal] Implement basic type consistency checks for Low level MH intrinsics" and 8224254 :"compiler/graalunit/HotspotJdk9Test.java is timing out intermittently" are closed as a dup of next graal update -- 8224254
 - 8066173 : "compiler/types/correctness/OffTest.java failed with assert" used wrong bug id to problem list tests on solaris-sparcv9

Thanks,
