Is your feature request related to a problem? Please describe. Our minimum viable product requires that application programmers opt-in to have their structures laid out randomly.

Describe the solution you'd like When Clang hands control to our plugin, we will check if the structure has the __randomize_layout attribute attached to it. If not, we will return false; and allow Clang to lay it out. If it does have the attribute, we will lay it out.

This will depend on #100 first, but this is the much more important issue.

I would finish off #100, branch and then develop this patch. We need to test that our plugin works with Clang V9 first.
