Sanjoy Das 79fa7ea8a7 [SCEV] Recognize simple br-phi patterns ... Summary: Teach SCEV to match patterns like ``` br %cond, label %left, label %right left: br label %merge right: br label %merge merge: V = phi [ %x, %left ], [ %y, %right ] ``` as "select %cond, %x, %y". Before this SCEV would match PHI nodes exclusively to add recurrences. This addresses PR25005.
