Stokhos: fix KokkosKernels #1959 #12207
Conversation
PR trilinos#12190 actually failed to fix KokkosSparse::spmv for Sacado scalar types, when building with Kokkos/KokkosKernels develop branch. This actually fixes that issue (tested with develop and master KokkosKernels) and is quite a bit cleaner (though it uses version macros that can be taken out for the 4.2 release).

PR #12190 failed to fix KokkosSparse::spmv for Sacado scalar types (issue kokkos/kokkos-kernels#1959), when building with Kokkos/KokkosKernels develop branch.
This actually fixes that issue (tested with develop and master KokkosKernels) and is quite a bit cleaner (though it uses version macros that can be taken out for the 4.2 release). Instead of trying to have a full set of spmv overloads with enable_ifs to match Sacado types, just have overloads for the actual impl (taking an exec space, controls and a rank tag) because all other overloads in KokkosKernels funnel down to those.
@trilinos/stokhos
Motivation
Fix incompatibility between Stokhos and KokkosKernels develop branch, in advance of the KokkosKernels 4.2 release.
Related Issues
Stakeholder Feedback
Testing
Built and ran all Stokhos unit tests cleanly with both Trilinos develop, with and without the develop branch of Kokkos/KokkosKernels.
