Yeah, seems likely. I think malloc gets lowered in SDISel to a call
though, so maybe it doesn't need it. I'm not sure what "malloc from
alternate address space" really means though. There can only be one
function named "malloc" :). Maybe LangRef should explicitly ban the
malloc instruction from returning a pointer to an alternate address
