Concurrency support for PNaCl ABI
Add portable support for concurrency in PNaCl's ABI:
- Promote volatile to atomic.
- Promote all memory ordering to sequential consistency.
- Rewrite all atomic operations to frozen NaCl intrinsics for pexe.
- Rewrite atomic intrinsics to LLVM instructions for translation.
This change also adds documentation to the PNaCl language reference, as
well as tests where it makes sense.
A future CL could clean up more of our code which mentions atomics,
volatiles, memory orderings.
Multiple reviewers because this is a big patch:
- eliben: LLVM-fu and ResolvePNaClIntrinsics.
- dschuff: ABI stability.
- mseaborn: ABI stability.
- sehr: Tron-duty (fight for the user's programs to work).
