Juneyoung Lee 6ad63606ea [CodeGenPrepare] Freeze condition when transforming select to br ... Summary: This is a simple fix for CodeGenPrepare that freezes branch condition when transforming select to branch. If it is not frozen, instsimplify or the later pipeline can potentially exploit undefined behavior. The diff shows optimized form becase D75859 and D76048 already made a few changes to CodeGenPrepare for optimizing freeze(cmp).
