Second attempt to "Rewrite atomic.h to use stdatomic.h."
This should not be committed until win_sdk and aarch64 builds are
fixed in the presence of this CL.
This reverts commit 2789faabfa9cdf16902a52a1de3fc4a7ae98efed.
We additionally remove uniprocessor support from the earlier CL,
thus avoiding a potential compiler code reordering issue.

Rewrite atomic.h to use stdatomic.h.
Replace atomic-inl.h with a file that just includes atomic.h.
Remove platform specific implementations.

Remove android_... store_barriers and 64-bit atomics.
These are no longer used, and we want to strongly discourage future use.
Keep the 32-bit variants while there are still uses. All users should move
to C11 or C++11 atomics.

AArch64: Add atomic functions
This patch adds atomic functions for AArch64. The functions
will be revisited later for potential optimizations using
assembly or otherwise.
This patch also introduces new 64-bit atomic functions for
LP64 platforms.

Qualify the source argument of atomic loads as a const pointer.
Also normalizes the opening brace placment in a few locations.

Define inline atomic operations for x86 and ARM.
This change moves the ARM definitions into GCC extended inline
assembler. In addition, the same set of x86 definitions are now
shared among all x86 targets.

Atomic/SMP update, part 2.
Added new atomic functions, renamed some old ones. Some #defines have
been added for backward compatibility.
Merged the pre- and post-ARMv6 implementations into a single file.
Renamed the semi-private __android_membar_full_smp to USE_SCREAMING_CAPS
since that's more appropriate for a macro.
Added lots of comments.
Note Mac OS X primitives have not been tested.

Atomic/SMP update.
Added atomic-inline.h. Added a platform-specific memory barrier call
there.
Added android_atomic_acquire_cmpxchg() and android_atomic_release_store().
Not tested on Mac OS X or SH.
Added memory barrier calls to linux-x86 atomics. Mac OS X has barrier
functions already. sh isn't really SMP-ready. linux-arm needs work
(to be done in a separate change).
Updated the makefile to make the SMP state visible to the code here.
Note that host binaries are NOT built with SMP enabled; while our hosts
are very likely SMP, it's not worth figuring out e.g. whether it's okay
to use the SSE2 mfence instruction or have to use something else. We
haven't had barriers enabled in host tools before, so there's probably
no need to stat now.
Removed quasiatomic 64-bit calls (now part of Dalvik).
