Some of the IR tests like testByte64ToLong512 are currently are failing on KNL due to following check 
https://github.com/openjdk/jdk/pull/10192/files#diff-33d0866101d899687e04303fb2232574f2cb796ce060528a243ebdc9903b01b1L2484

since source and destination ideal types are different (TypeVect vs TypeVectMask),  can you kindly change the feature check for relevant IR tests to avx512vl  till we remove that limitation.
