Note that while working on mozilla, I noticed that SUN's compiler extends the
toplevel asm syntax by allowing parameters (and the usual %n references to
them).  It probably makes sense to adopt this syntax in future.  Until then
Iguess we will need to explain users that toplevel asm statements basically
exists outside of LTO unit and thus everything used by them needs to be marked
as externally visible.
