After https://github.com/openjdk/valhalla/pull/409 and https://github.com/openjdk/valhalla/pull/414 have been integrated, we need to fix the JIT code as well. This mostly means re-applying the old changes from https://github.com/openjdk/valhalla/commit/22dd0da1 and https://github.com/openjdk/valhalla/commit/e895128f and adjust them to the current implementation.

All compiler tests now pass except for `TestNullableInlineTypes`, `TestNullableArrays` and `TestIntrinsics` which need reflection support. The corresponding C2 intrinsics are still broken. I'll fix them with [JDK-8267932](https://bugs.openjdk.java.net/browse/JDK-8267932) once reflection support is available.
