Currently the only way to print native methods is to use the global `-XX:+PrintAssembly` option. But this prints *all* compiled methods which can be too much if we're just interested in a specific native wrapper. There's no reason to not apply `-XX:CompileCommand` options correctly to native methods as well.

Hi @simonis , I encountered a build error after this commit. When `make images` using congiure `--with-jvm-variants=core`, the error is as follows:
