Details: - Changed the way virtual microkernels are handled in the context. Previously, there were query routines such as bli_cntx_get_l3_ukr_dt() which returned the native ukernel for a datatype if the method was equal to BLIS_NAT, or the virtual ukernel for that datatype if the method was some other value. Going forward, the context native and virtual ukernel slots will both be initialized to native ukernel function pointers for native execution, and for non-native execution the virtual ukernel pointer will be something else. This allows us to always query the virtual ukernel slot (from within, say, the macrokernel) without needing any logic in the query routine to decide which function pointer (native or virtual) to return. (Essentially, the logic has been shifted to init-time instead of compute-time.) This scheme will also allow generalized virtual ukernels as a way to insert extra logic in between the macrokernel and the native microkernel. - Initialize native contexts (in bli_cntx_ref.c) with native ukernel function addresses stored to the virtual ukernel slots pursuant to the above policy change. - Renamed all static functions that were native/virtual-ambiguous, such as bli_cntx_get_l3_ukr_dt() or bli_cntx_l3_ukr_prefers_cols_dt() pursuant to the above polilcy change. Those routines now use the substring "get_l3_vir_ukr" in their name instead of "get_l3_ukr". All of these functions were static functions defined in bli_cntx.h, and most uses were in level-3 front-ends and macrokernels. - Deprecated anti_pref bool_t in context, along with related functions such as bli_cntx_l3_ukr_eff_dislikes_storage_of(), now that 1m's panel-block execution is disabled.
