; If a function has linkage "available_externally", make sure that a dllimport
; attribute is not dropped. The library definition (with a dllexport attribute)
; might be in a shared library, rather than merged into this module. Since we
; can't guaranty the definition is available locally, the dllimport attribute
; may be used by later passes and should be preserved.
