Jiaming Yuan	0d0abe1845	Support optimal partitioning for GPU hist. (#7652 ) * Implement `MaxCategory` in quantile. * Implement partition-based split for GPU evaluation. Currently, it's based on the existing evaluation function. * Extract an evaluator from GPU Hist to store the needed states. * Added some CUDA stream/event utilities. * Update document with references. * Fixed a bug in approx evaluator where the number of data points is less than the number of categories.	2022-02-15 03:03:12 +08:00
