[PATCH] D42788: [SDAG] Legalize all CondCodes by inverting them and/or swapping operands

[Derek Schuff via Phabricator via llvm-commits]

So, it turns out that this actually does change functionality on targets (such as WebAssembly) that use the expansion for unordered comparisons because it tries inverting the condition before falling all the way through to line 1680. This actually results in better code for wasm; see https://reviews.llvm.org/rL324305
