Field G. Van Zee e2e9d64a63 Load balance thread ranges for arbitrary diagonals. ...

Details:
- Expanded/updated interface for bli_get_range_weighted() and
  bli_get_range() so that the direction of movement is specified in the
  function name (e.g. bli_get_range_l2r(), bli_get_range_weighted_t2b())
  and also so that the object being partitioned is passed instead of an
  uplo parameter. Updated invocations in level-3 blocked variants, as
  appropriate.
- (Re)implemented bli_get_range_*() and bli_get_range_weighted_*() to
  carefully take into account the location of the diagonal when computing
  ranges so that the area of each subpartition (which, in all present
  level-3 operations, is proportional to the amount of computation
  engendered) is as equal as possible.
- Added calls to a new class of routines to all non-gemm level-3 blocked
  variants:
    bli_<oper>_prune_unref_mparts_[mnk]()
  where <oper> is herk, trmm, or trsm and [mnk] is chosen based on which
  dimension is being partitioned. These routines call a more basic
  routine, bli_prune_unref_mparts(), to prune unreferenced/unstored
  regions from matrices and simultaneously adjust other matrices which
  share the same dimension accordingly.
- Simplified herk_blk_var2f, trmm_blk_var1f/b as a result of more the
  new pruning routines.
- Fixed incorrect blocking factors passed into bli_get_range_*() in
  bli_trsm_blk_var[12][fb].c
- Added a new test driver in test/thread_ranges that can exercise the new
  bli_get_range_*() and bli_get_range_weighted_*() under a range of
  conditions.
- Reimplemented m and n fields of obj_t as elements in a "dim"
  array field so that dimensions could be queried via index constant
  (e.g. BLIS_M, BLIS_N). Adjusted/added query and modification
  macros accordingly.
- Defined mdim_t type to enumerate BLIS_M and BLIS_N indexing values.
- Added bli_round() macro, which calls C math library function round(),
  and bli_round_to_mult(), which rounds a value to the nearest multiple
  of some other value.
- Added miscellaneous pruning- and mdim_t-related macros.
- Renamed bli_obj_row_offset(), bli_obj_col_offset() macros to
  bli_obj_row_off(), bli_obj_col_off().
