- Added the support for Tiny-CGEMM as part of the existing macro based Tiny-GEMM interface. This involved definining the appropriate AVX2/AVX512 lookup tables and functions for the target architectures(as per the design), for compile-time instantiation and runtime usage. - Also extended the current Tiny-GEMM design to incorporate packing kernels as part of its lookup tables. These kernels will be queried through lookup functions and used in case of wanting to support non-trivial storage schemes(such as dot-product computation). - This allows for a plug-and-play fashion of experimenting with pack and outer product method against native inner product implementations. - Further updated the existing AVX512 pack routine that packs the A matrix (in blocks of 24xk). This utilizes masked loads/stores instructions to handle fringe cases of the input(i.e, when m < 24). - Also added the AVX512 outer product kernels for CGEMM as part of the ZEN4 and ZEN5 contexts, to handle RRC and CRC storage schemes. This is facilitated through optional packing of A matrix in the SUP framework.
