`TestIntrinsics.java` fails after [JDK-8269956](https://bugs.openjdk.java.net/browse/JDK-8269956) which replace some usages of `MyValue.class` by `MyValue.class.asValueType()`. The problem is that `asValueType()` is not always inlined by C2 and therefore IR verification fails.

This patch intrinsifies the methods similar to what we did in old L/Q world (https://github.com/openjdk/valhalla/commit/e895128f). I've also modified the test to consistently use `asPrimaryType`/`asValueType`.

Thanks,
Tobias
