Sorry, not quiet. What you get is

leaq    foo(%rip), %rax

Since it is still assuming foo is a position in the file.

So yes, we need a way to declare an absolute value. If we can declare
it, we may as well use the same construct to define it.

I guess the only issue then is that the current implementation of
alias becomes even more needlessly generic :-(
