[cfe-dev] atomic intrinsics

[Howard Hinnant]

In the hopes of clarification, I've put three design descriptions up at:

http://libcxx.llvm.org/atomic_design.html

A and/or B is what Eric proposed.  C is what I've been working toward.  A is my preference.  But I can't implement A without buy-in from the front end team.  Heck, I can't actually implement any of them without said buy-in. :-)  I chose C originally because that was where I thought I could most likely get buy-in.

If any of those docs are unclear, just let me know and I'll attempt to clarify what is intended.
