This PR adds a performance-oriented optimization to differentiate between uniform and divergent branches. Uniform branches are jumps that will be taken by all active lanes in a warp in all cases. This PR adds this new performance-driven pass to the O2 pipeline and is designed to reduce register consumption and improve control-flow performance of kernels for NVIDIA GPUs.
