Also consider creating copies of jdk/java/lang/Float/Binary16Conversion*.java tests in compiler/intrinsics/ and modify them to compare results from Interpreter, runtime and JITed code. We run compiler/intrinsics/ tests with different SSE and AVX settings to make sure they work in all cases. ------------- Changes requested by kvn (Reviewer). PR: https://git.openjdk.org/jdk/pull/12704
