[foreign] RFR: 8225686: Pointer access struct field failed with SecurityManager

[Henry Jen]

Hi,

Please review webrev[1] for JDK-8225686[2].

The fix is to ensure pointer access works under SecurityManager, the test case should work with java.foreign.Scope permission granted, but there are two area where SecurityException could be thrown.

Also in the webrev, there is a cleanup for libeling binding to remove disposed TU from the ClangUtils.

Cheers,
Henry
