Fused GEMM+GEMM (#351)
* initial stub for gemm_gemm_xdl_cshuffle * set up example code * compiles * prevent integer overflow * harmonize interface between ref_gemm and ref_batched_gemm * batched_gemm_gemm * fix example * host tensor gen: diagonal pattern in lowest two-dimensions only * make c descriptors containing only integral constants * clean up * add BlockwiseGemmXdlops_v2 while exploring an unified approach * implement proper interface * tidy up example * fix compilation warnings * coarsely controlled 2nd gemm padding * remove rocm-cmake's hard requirement for certain revision * clang-format * resolve merge conflict * fix compilation error on gfx10 * adds acc0 elementwise op to interface * add gemm_gemm instances and tests * avoid LDS data hazard * fix build Co-authored-by: Chao Liu <chao.liu2@amd.com>
