I've updated the explicit_bero patches for the change to how .abilist

controversial string2.h optimization into its own patch so it can be
discussed separately from the merits of the interface.
Zack, can you propose a stripped-down version of the patch with no
unrelated test changes?
I need the explicit_bzero compiler barrier for writing some tests.
I think the API is as good as it gets. The implementation may need some
changes in the future (e.g., clearing all callee-saved registers), but
that depends on how things work out on the GCC side and does not seem
required for a first implementation.
