1. In zgemm, mkernel outperforms nkernel for both m > n, and n > m.
2. Irrespective of mu and nu sizes, mkernel is forced for zgemm based on analysis done.

1. SquarePacked algorithm focuses on efficient zgemm/dgemm implementation for square matrix sizes (m=k=n)
2. Variation of 3m algorithm (3m_sqp) is implemented to allow single load and store of C matrix in kernel.
3. Currently the method supports only m multiple of 8. Residues cases to be implemented later.
4. dgemm Real kernel (dgemm_sqp) implementation without alpha, beta multiple is done,
    since real alpha and beta scaling are in 3m_sqp framework.
5. gemm_sqp supports dgemm when alpha = +/-1.0 and beta = 1.0.

5. sqp framework done from dgemm and zgemm.
6. sqp kernels moved to seperate kernel file.
7. residue kernel core added to handle mx<8.
8. multi-instance tuning for 3m_sqp done.
9. user can set env "BLIS_MULTI_INSTANCE" to 1 for better multi-instance behavior of 3m_sqp.
