Hugo MeilandandCursor 23f832c464 Wire CORTEXA72 6x8 blocking and DYNAMIC_ARCH dispatch 
Give CORTEXA72 its own param.h block (UNROLL 6x8, P=120 Q=240, R=4096
shared-L2 / R=768 single-core), add it to DYNAMIC_CORE, and stop
aliasing gotoblas_CORTEXA72 to A57 so DYNAMIC_ARCH can select the new
kernels on MIDR 0xd08.

Fadi Arafeh f30202b705 Accelerate SVE128 SBGEMM/BGEMM 
This accelerates SBGEMM/BGEMM by extending the existing 8x4 kernel to 8x8 (unrolling N by 8)

Not sure if it's a good idea to delete the previous 8x4 kernel?

Here are the speedups on single core Neoverse-V2 (SVE128) compared to prev state:

Per-shape speedup
  M=N=K=64: SBGEMM 1.164x (16.42%), BGEMM 1.133x (13.30%)
  M=N=K=128: SBGEMM 1.220x (22.02%), BGEMM 1.186x (18.56%)
  M=N=K=256: SBGEMM 1.241x (24.08%), BGEMM 1.235x (23.54%)
  M=N=K=512: SBGEMM 1.240x (23.95%), BGEMM 1.227x (22.75%)
  M=N=K=1024: SBGEMM 1.251x (25.11%), BGEMM 1.232x (23.23%)
  M=N=K=2048: SBGEMM 1.235x (23.47%), BGEMM 1.246x (24.64%)

Chris SidebottomandYe Tao f95e7b0e32 Add infrastructure for BGEMM 
Setting up all the infrastructure for BGEMM support in OpenBLAS, hopefully I found all the right places.

Derived mostly from the previous work done in https://github.com/OpenMathLib/OpenBLAS/pull/5287
