; FIXME:
; The C1 direction is incorrect.
; When moving an alias to an existing module and we want to discard the aliasee
; (the C2 case), the IRMover knows to copy the aliasee as internal.
; When moving a replacement to an aliasee to a module that has an alias (C1),
; a replace all uses with blindly changes the alias.
; The C1 case doesn't happen when using a system linker with a plugin because
; the linker does full symbol resolution first.
; Given that this is a problem only with llvm-link and its 1 module at a time
; linking, it should probably learn to changes the aliases in the destination
; before using the IRMover.
