This PR adds copy_if family to use reduce_then_scan algorithm where it is beneficial.
Moves all algorithm selection decisions to
__parallel_copy_if, and unifies range API to also use this function. Adding support for an assignment operator for single work group copy_if. This allows us to unify the algorithmic selection, and provide performance improvements to the ranges API.Adds
__parallel_reduce_then_scan_copyfunction which will be used by partition and unique in the future to take advantage of shared functionality.This PR is targeted to #1762, to allow for a clean diff, and is a part of the following sequence of PRs meant to be merged in order:
#1769 [MERGED]
Relocate __lazy_ctor_storage to utils header#1770 [MERGED]
