daichengrong aa967ef6ba Optimize ZROT_RVV for the non-unit-stride case
Optimize the RVV implementation of ZROT when inc_x and inc_y are
non-unit strides (inc_x != 1, inc_y != 1).

Reorder several operations to reduce vector register pressure and
avoid unnecessary vector register spill to the stack. This helps GCC
keep vector values in registers and reduces redundant spill/reload
instructions, improving runtime performance.

No functional change.

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%)
