Craig Topper ef08aec935 [LoopIdiomRecognize] Add a test case showing a loop we turn into ctlz that we shouldn't.
This loop executes one iteration without checking the input value. This produces a count of 1 for an input of 0 and 1. We are turning this into 32 - ctlz(n), but that returns 0 if n is 0.
