[PATCH] D111160: [UnknownProvenance] Add LLVM-IR support for unknown_provenance

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

Should there be a verifier change to ensure that it is *actually* only used in the provenance operand, and not as a pure pointer,
or can it be PHI'd/select'ed from multiple variants?
