RFR: 8303810: Restore attribute positions after JDK-8303839 to match JDK-8302124 [v3]

[Julian Waters]

> [JDK-8303839](https://bugs.openjdk.org/browse/JDK-8303839)'s revert of [[noreturn]] attributes also moved their already existing attributes back to behind their corresponding methods, they should be restored to where [JDK-8302124](https://bugs.openjdk.org/browse/JDK-8302124) requires them to be. Also fixes attribute from [JDK-8292269](https://bugs.openjdk.org/browse/JDK-8292269)
