Details: - Lifted the constraint that 1m only be used when all operands' storage datatypes (along with the computation datatype) are equal. Now, 1m may be used as long as all operands are stored in the complex domain. This change largely consisted of adding the ability to pack to 1e and 1r formats from one precision to another. It also required adding logic for handling complex values of alpha to bli_packm_blk_var1_md() (similar to the logic in bli_packm_blk_var1()). - Fixed a bug in several virtual microkernels (bli_gemm_md_c2r_ref.c, bli_gemm1m_ref.c, and bli_gemmtrsm1m_ref.c) that resulted in the wrong ukernel output preference field being read. Previously, the preference for the native complex ukernel was being read instead of the pref for the native real domain ukernel. This bug would not manifest if the preference for the native complex ukernel happened to be equal to that of the native real ukernel. - Added support for testing mixed-precision 1m execution via the gemm module of the testsuite. - Tweaked/simplified bli_gemm_front() and bli_gemm_md.c so that pack schemas are always read from the context, rather than trying to sometimes embed them directly to the A and B objects. (They are still embedded, but now uniformly only after reading the schemas from the context.) - Redefined cpp macro bli_l3_ind_recast_1m_params() as a static function and renamed to bli_gemm_ind_recast_1m_params() (since gemm is the only consumer). - Added 1m optimization logic (via bli_gemm_ind_recast_1m_params()) to bli_gemm_ker_var2_md(). - Added explicit handling for beta == 1 and beta == 0 in the reference gemm1m virtual microkernel in ref_kernels/ind/bli_gemm1m_ref.c. - Rewrote various level-0 macro defs, including axpyris, axpbyris, scal2ris, and xpbyris (and their conjugating counterparts) to explicitly support three operand types and updated invocations to xpbyris in bli_gemmtrsm1m_ref.c. - Query and use the storage datatype of the packed object instead of the storage datatype of the source object in bli_packm_blk_var1(). - Relocated and renamed frame/ind/misc/bli_l3_ind_opt.h to frame/3/gemm/ind/bli_gemm_ind_opt.h. - Various whitespace/comment updates.
