- Added a new GEMV kernel with MR = 8 which will be used
for cases where n=1.
- Modified GEMM and GEMV framework to choose right GEMV kernel
based on compile-time and run-time architecture parameters. This
had to be done since GEMV kernels are not stored-in/retrieved-from
the cntx.
- Added a pack kernel that packs A matrix from col-major to row-major
using AVX2 instructions.
