[PATCH] D62819: [SCCP] Add UnaryOperator visitor to SCCP

[Florian Hahn via Phabricator via llvm-commits]

fhahn added inline comments.

----------------
I think it would be better to explicitly check the return value, instead of relying on `grep`. Also, would it be possible to add another case where the operand to fneg itself needs to be propagated before we simplify fneg?
