I will try to move this into the mainline ahead of the JEP PR (process allowing). As well as another testing coverage patch for nested structs/unions: https://github.com/openjdk/panama-foreign/pull/780.

WRT this: we had intrinsification in the past as well (https://github.com/openjdk/panama-foreign/pull/609), but it was removed since we also removed 'trivial' calls at some point (and then the intrinsics were not used). Now that trivial calls are back on the menu, it might be interesting to look at re-adding intrinsics as well.
