mtklein a669bc7a7a Atomics overhaul.
This merges and refactors SkAtomics.h and SkBarriers.h into SkAtomics.h and
some ports/ implementations. The major new feature is that we can express
memory orders explicitly rather than only through comments.

The porting layer is reduced to four template functions:
  - sk_atomic_load
  - sk_atomic_store
  - sk_atomic_fetch_add
  - sk_atomic_compare_exchange
From those four we can reconstruct all our previous sk_atomic_foo.

There are three ports:
  - SkAtomics_std:    uses C++11 <atomic>,             used with MSVC
  - SkAtomics_atomic: uses newer GCC/Clang intrinsics, used on not-MSVC where possible
  - SkAtomics_sync:   uses older GCC/Clang intrinsics, used where SkAtomics_atomic not supported

No public API changes.
