Summary: Have basic reduction fusion working, and have improved code generator to approach performance of eager mode reductions. Coming soon will be pointwise-reduction fusions in a way that should prevent the possibility of hitting regressions. Also working on performant softmax kernels in the code generator which may be our next fusion target.
