Hans Wennborg 57933e3481 SimplifyCFG: Don't generate invalid code for switch used to initialize
two variables where the first variable is returned and the second
ignored.

I don't think this occurs in practice (other passes should have cleaned
up the unused phi node), but it should still be handled correctly.

Also make the logic for determining if we should return early less
sketchy.
