rsmith added a comment.

What are the expected semantics in this case? Is this:

- the function is still the builtin, but if it ends up being a libcall, call a 
function with a different asm name, or
- the function is not considered to be the builtin any more, or
- something else?

I think this patch is approximately the first thing, but it's also cutting off 
emission for cases where we wouldn't emit a libcall. Should we make that 
distinction?
