Field G. Van Zee 87db5c048e Changed usage of virtual microkernel slots in cntx.
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.
