From-SVN: r224119

This patch removes the special casing for targets with relaxed
memory ordering and handles guard accesses with equivalent
atomic load acquire operations. In this process we change the
algorithm to load the guard variable with an atomic load that
has ACQUIRE semantics.

This then means that on targets which have weak memory models, the
fast path is inlined and can directly use a load-acquire instruction
where available (and yay! one more hook gone).
