[PATCH] Adding diversity for security

[Alp Toker]

Hi Nadav,

Do you think this is satisfactory now? I don't have a clear idea of 
whether it's still intrusive in terms of the backend or if that's been 
addressed.

It does look like the patch has come a long way so in interest of 
unblocking the review queue I've offered to help Julian work on 
additional requirements like making the RNG non-global after the initial 
patches land in LLVM and clang if the feature seems desirable overall.

What do you think?

Alp.
