Attilio Rao 4dc32a7398 MFC r197803, r197824, r197910:
Per their definition, atomic instructions used in conjuction with
memory barriers should also ensure that the compiler doesn't reorder paths
where they are used.  GCC, however, does that aggressively, even in
presence of volatile operands.  The most reliable way GCC offers for avoid
instructions reordering is clobbering "memory".
Not all our memory barriers, right now, clobber memory for GCC-like
compilers.
Fix these cases.
