I had to take a guess at the right component, based on a couple other
std::atomic bugs I looked at.  Apparently I picked wrong, if libstdc++ really
is just the headers and not compiler internals at all.  Can someone please mark
the appropriate component?  I mostly just look at compiler asm output, not the
real internals.
