Yeah, that's what happens with this patch; Reference binds against an 
`llvm::Function` declaration, linker resolves it to the actual ifunc in another 
translation unit and therefore emits IFUNC relocation.

Thinking about it more, this is inelegant. I would have liked the reference 
against the `cpu_specific` to bind against a plain "FOO" function declaration 
and not "FOO.ifunc", and 'upgrade' it later once a cpu_dispatch is encountered.
To my understanding, this is actually the reason 
https://reviews.llvm.org/D67058 added the plain-name alias.

I'll try to see if I can rework that.
