[Roman Lebedev via Phabricator via llvm-commits]

This revision now requires changes to proceed.

Please,

1. either add a comment explaining why the one-use check needed
2. or rewrite the transform the right way, so that the lack of one-use check shows up as extra instruction bloat and not a miscompilation
