I am with Anton on this. I don't think we should have a user visible
switch for enabling/disabling the support in a particular
architecture. I think the complete decision tree is
if (llvm doesn't support the attribute on this architecture for some reason)

don't put it on the IL).
put the attribute on the IL and produce unreachable instead of ret
if (gcc doesn't support this attribute in this arch)
produce an externsion warning.
The only point there was disagreement was on the extension warning. In
any case, I am ok with compromising on that if you are ok with
