[LLVMdev] Phi + Select Optimization
...a'. In the other case, the phi depends on itself. Thus, we can remove it. The attached patch implements that. This is really useful in vectorized code, when there are a lot of selects in order to implement "vectorized control-flow". Also, there is a minor enhancement which improves SimplifySelectInst to also simplify when the condition is a vector of all true or false values.
