Konstantin Belousov a58679a93b Complete r323772 on amd64.
Compilers are allowed to combine plain reads into group operations,
e.g. 64bit element copies of one array into another can be
legitimately optimized back to a memcpy() call, which r323772 tried to
prevent.

Qualify accesses to LDT descriptors with volatile dereference to
ensure that each write indeed occurs.  After that, our usual claim of
native-size aligned writes being atomic applies.

This is equivalent to atomic_store(memory_order_relaxed) C11 accesses,
but our machine/atomic.h does not provide corresponding primitive.
