f38e88bc29 Allow optional memory ordering to atomic methods
Currently only C11 atomics make use of the memory order. If not
specified, it defaults to almemory_order_seq_cst.

6ce464aed8 Avoid a CPU memory fence, and better order memory barriers to accesses
Code produced by GCC 4.9's C11 atomic implementation does not seem to add a
CPU memory fence even with memory_order_seq_cst. Unnecessary memory fences
will be a detriment to performance, so they should only be added if needed.
