Details: - Implemented algorithmic optimizations for trmm and trsm whereby the right side case is now handled explicitly, rather than induced indirectly by transposing and swapping strides on operands. This allows us to walk through the output matrix with favorable access patterns no matter how it is stored, for all parameter combinations. - Renamed trmm and trsm blocked variants so that there is no longer a lower/upper distinction. Instead, we simply label the variants by which dimension is partitioned and whether the variant marches forwards or backwards through the corresponding partitioned operands. - Added support for row-stored packing of lower and upper triangular matrices (as provided by bli_packm_blk_var3.c). - Fixed a performance bug in bli_determine_blocksize_b() whereby the cache blocksize extensions (if non-zero) were not being used to appropriately size the first iteration (ie: the bottom/right edge case). - Updated comments in bli_kernel.h to indicate that both MC and NC must be whole multiples of MR AND NR. This is needed for the case of trsm_r where, in order to reuse existing left-side gemmtrsm fused micro-kernels, the packing of A (left-hand operand) and B (right-hand operand) is done with NR and MR, respectively (instead of MR and NR).
