Summary: This is patch #3 of the new DivergenceAnalysis <https://lists.llvm.org/pipermail/llvm-dev/2018-May/123606.html> The GPUDivergenceAnalysis is intended to eventually supersede the existing LegacyDivergenceAnalysis. The existing LegacyDivergenceAnalysis produces incorrect results on unstructured Control-Flow Graphs: <https://bugs.llvm.org/show_bug.cgi?id=37185> This patch adds the option -use-gpu-divergence-analysis to the LegacyDivergenceAnalysis to turn it into a transparent wrapper for the GPUDivergenceAnalysis.
