I've posted already a WIP version of atomics-as-support library for amd64. 
Attached it again.

(It needs some scaffolding from the 
header--__builtin_constant_p/_Static_assert/sizeof shenanigans--but 
nothing too bad.)

Implementing them as functions does harm performance, but maybe that's not 
a very big problem since the atomic itself incurs a decent performance 
hit?
