Content

Team-level implementation and tests for:

• Kokkos_Copy.hpp
• Kokkos_CopyN.hpp
• Kokkos_CopyBackward.hpp
• Kokkos_CopyIf.hpp
• Kokkos_UniqueCopy.hpp
• Kokkos_Remove.hpp
• Kokkos_RemoveIf.hpp
• Kokkos_RemoveCopy.hpp
• Kokkos_RemoveCopyIf.hpp

Technical comments

• this PR is not split any further because of the following dependencies:

  • Kokkos_UniqueCopy.hpp: needs copy
  • Kokkos_Remove.hpp: needs copy_if
  • Kokkos_RemoveIf.hpp: needs copy_if and count_if
  • Kokkos_RemoveCopy.hpp: needs copyif
  • Kokkos_RemoveCopyIf.hpp: needs copyif

• the change class -> typename and the enable if defaulted in the template parameters comes from this request

• the code duplication is intentional and agreed upon after the long discussion in here

• tests are run for both contiguous views and strided views

Other comments

• all team-level PRs are tracked in: Team-level std algorithms PRs: issue tracker  #6352

• this comes from breaking apart team impl of std algorithms  #5150

Possible conflicts

Implementation-wise, this has not conflict with other team-level PRs so it could be merged independently.
However, a trivial conflict in the CMakeLists inside the unit test occurs if another of the team-level PRs is merged before this because each team-level PR adds test using a specific "label". Resolving this is trivial.
