[PATCH] D68408: [InstCombine] Negator - sink sinkable negations

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

Hmm, that's a bit more complicated than I hoped it would be... but I don't see any obvious way to simplify it.

It looks like this speculatively creates new instructions, then erases them on failure?
