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
