RFR: JDK-8298880: VectorLogicalOpIdentityTest.java IR test incorrectly use avx3 instead of avx512

[Damon Fenacci]

A few tests of _compiler/vectorapi/VectorLogicalOpIdentityTest.java_ (`testAndMaskSameValue1`, `testAndMaskSameValue2`, `testAndMaskSameValue3`, `testOrMaskSameValue1`, `testOrMaskSameValue2`, and `testOrMaskSameValue3`) use _avx3_ in the `applyIfCPUFeatureOr` IR filter but the actual CPU extension filter is _avx512_.

Changing _avx3_ to _avx512_ in the `applyIfCPUFeatureOr` filter.
