Here, we capture nf, then the use of the proxy decays to a constant during
semantic processing of +nf. Since we saw some decay from proxy to constant,
we walk through the lambda body to see which proxies are still used, but we
weren't walking into subtrees of DECL_EXPR at all, so we missed the use of
&nf in the initializer of y, and removed the capture. But then at
instantiation time we try to use nf, don't have a proxy anymore, and ICE.

GCC has supported the __atomic intrinsics since 4.7. They are better
than the __sync intrinsics in that they specify a memory model and,
more importantly for our purposes, they are reliably implemented
either in the compiler or in libatomic.

Some people use the -fdump-rtl-combine dumps (instead of the -da or
-fdump-rtl-combine-all dump), but the "Can't combine iN into iM"

printed otherwise. So let's change that.
