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

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri updated this revision to Diff 256801.
lebedev.ri added a comment.

Handle PHI's, too.
Strangely, i distinctively recall seeing some preexisting test
causing an endless cycle, but i'm no longer observing that problem.
