Thanks Andrew. Here's the updated patch, as checked in. This removes
one level of cruft WRT atomic configure-ness (leaving us with the most
primordial...).

That would be why cppbuiltin.c, defining __SIZEOF_POINTER__, needs to use
the POINTER_SIZE macro instead of directly using ptr_type_node. You may
need to do something similar.

Anyway, it looks like __atomic_always_lock_free doesn't fold early
enough to be usable by the preprocessor like that even with my earlier
version. ugg. I think I can get something defined in cpp-builtins
that we can use. We're going to need it

Here's the first step in making the libstdc++ atomic configure bits into
something that makes more sense. This consolidates the builtin parts of
the configury, such that builtins mean C++11 atomics, not C++11 atomics
mixed with pre-C++11 atomics.
