Optimize Neon reductions in sum_neon.h using ADDV instruction Use the AArch64-only ADDV and ADDLV instructions to accelerate reductions that add across a Neon vector in sum_neon.h. This commit also refactors the inline functions to return a scalar instead of a vector - allowing for optimization of the surrounding code at each call site.
