Details: - Added support for being able to duplicate (broadcast) elements in memory when packing matrix B (ie: the left-hand operand) in level-3 operations. This turns out advantageous for some architectures that can afford the cost of the extra bandwidth and somehow benefit from the pre-broadcast elements (and thus being able to avoid using broadcast-style load instructions on micro-rows of B in the gemm microkernel). - Support optionally disabling right-side hemm and symm. If this occurs, hemm_r is implemented in terms of hemm_l (and symm_r in terms of symm_l). This is needed when broadcasting during packing because the alternative--supporting the broadcast of B while also allowing matrix B to be Hermitian/symmetric--would be an absolute mess. - Support alignment factors for packed blocks of A, B, and C separately (as well as for general-purpose buffers). In addition, we support byte offsets from those alignment values (which is different from aligning by align+offset bytes to begin with). The default alignment values are BLIS_PAGE_SIZE in all four cases, with the offset values defaulting to zero. - Pass pack_t schema into bli_?packm_cxk() so that it can be then passed into the packm kernel, where it will be needed by packm kernels that perform broadcasts of B, since the idea is that we *only* want to broadcast when packing micropanels of B and not A. - Added definition for variadic bli_cntx_set_l3_vir_ukrs(), which can be used to set custom virtual level-3 microkernels in the cntx_t, which would typically be done in the bli_cntx_init_*() function defined in the subconfiguration of interest. - Added a "broadcast B" kernel function for use with NP/NR = 12/6, defined in in ref_kernels/1m/bli_packm_cxk_bb_ref.c. - Added a gemm, gemmtrsm, and trsm "broadcast B" reference kernels defined in ref_kernels/3/bb. (These kernels have been tested with double real with NP/NR = 12/6.) - Added #ifndef ... #endif guards around several macro constants defined in frame/include/bli_kernel_macro_defs.h. - Defined a few "broadcast B" static functions in frame/include/level0/bb for use by "broadcast B"-style packm reference kernels. For now, only the real domain kernels are tested and fully defined. - Output the alignment and offset values for packed blocks of A and B in the testsuite's "BLIS configuration info" section. - Comment updates to various files. - Bumped so_version to 3.0.0.
