* use 'sweep once' softmax kernel where applicable * threadwise copy's dst buffer can specify invalid element value * add int8 in/out float compute softmax support give a bit of leeway for int absolute tolerance as there's a single data point of all test cases showing off-by-1 error * format * softmax inherits DeviceNormalization * softmax profiler stub * tighten up reference softmax interface * example prints tensor dimension * add fp32 to softmax profiler * rename header * hook with ckProfiler * format * resolve merge conflict * resolve merge conflicts * update normalization profiler help string * resolve conflict * typo * remove residual * softmax profiler: address feedback * test for mixed precision input/output * fully qualify ck::math::isnan * add comment for device normalization interface * revise wording * constness for alpha/beta scaler pointer
