Actually, what I think David is suggesting is that if we see a
call to bzero, and we try to interpret it as a builtin, and we
don't expand it inline, that we proceed with the original call
to bzero, which would not be a namespace violation.

Can we distinguish a call to __builtin_bzero and bzero?  If so
this should be fairly easy.  Otherwise...
