; It's invalid to have a non-intrinsic call with a metadata argument,
; so it's unproductive to replace the users of the intrinsic
; declaration with undef.
; Intrinsic calls can't be uniformly replaced with undef without invalidating
; IR (eg: only intrinsic calls can have metadata arguments), so ensure they are
; not replaced. The whole call instruction can be removed by instruction
; reduction instead.
