Details: - Added the ability to induce complex domain level-3 operations via new virtual complex micro-kernels which are implemented via only real domain micro-kernels. Two new implementations are provided: 4m and 3m. 4m implements complex matrix multiplication in terms of four real matrix multiplications, where as 3m uses only three and thus is capable of even higher (than peak) performance. However, the 3m method has somewhat weaker numerical properties, making it less desirable in general. - Further refined packing routines, which were recently revamped, and added packing functionality for 4m and 3m. - Some modifications to trmm and trsm macro-kernels to facilitate indexing into micro-panels which were packed for 4m/3m virtual kernels. - Added 4m and 3m interfaces for each level-3 operation. - Various other minor changes to facilitate 4m/3m methods.
