* Use new-new-mma also for MLA=3, and use mask bounds
This gives us ~25% better PP at 32k tokens compared to main
* This seems better

This commit enables IQK quantization operations on ARM-based systems,
specifically tested on NVIDIA DGX Spark with GB10 Grace Blackwell.
Changes:
- Enable IQK_IMPLEMENT macro for ARM NEON operations
- Add arm_neon.h header include for ARM SIMD intrinsics
- Fix compilation errors related to missing NEON types and functions
Build requirements for ARM:
cmake .. -DGGML_CUDA=ON \
-DCMAKE_CXX_FLAGS="-march=armv8.2-a+dotprod+fp16" \
-DCMAKE_C_FLAGS="-march=armv8.2-a+dotprod+fp16"
Tested on:
- Platform: NVIDIA DGX Spark (aarch64)
- CPU: GB10 Grace Blackwell Superchip
- Memory: 128GB unified memory
Fixes build errors:
- 'float32x4_t' does not name a type
- 'vld1q_f32' was not declared in this scope
- 'v_expf' was not declared in this scope
- Missing FP16 NEON intrinsics

* Use mmq_id in mul_mat_id
* Better
* Also use it in the fused up+gate op
* Better -no-fmoe TG on CUDA
Still much slower than -fmoe, but abot 20-25% faster than what
we had before.

* Merge Q and K into a single tensor
* Make V mul mat follow QK mul mat
so they can be fused, which gives a slightly bbetter TG performance.

* Introducing rope cache
When computing RoPE, the rotation angles in each layer
are exactly the same, and only depend on the token positions
(and other constant, model dependent parameters).
So, I wonder, why don't we compute the angles just once
and then reuse for the Q and K RoPE in each layer?
This commit does it as a POC on the CPU, and uses it in
the Qwen3-MoE compute graph.
* cuda: neox works
* WIP
* rope_cache: norm works
* Fused rope+rope
* Fused rope+rope (norm)
* Fused rms+rms+rope+rope (neox) - not working
* WIP
* Also qwen3
* Add command line arg to disable rope cache
* Disable RoPE cache if rope type is not neox or norm
* Add missing break after merge with main
* Fused fused_rms+fused_rms+rope+rope (with -mqkv)
* Fused fused_rms+fused_rms+rope+rope (without -mqkv)

* POC: merge Q, K, V into a single, contiguous tensor
Done just for Qwen3-MoE, where I see a 4% uplift in TG.
PP performance gain is sub-percent, if any.
Still, it seems it makes sense to do it in general given
the TG performance gain.
* WIP
* merge_qkv: it works for gpt-oss
...but we see a smaller TG gain (~1.5%)
* WIP
* Don't ignore the return value of create_tensors()
else, when q, k, v get merged and we are running on the CPU,
we get a crash because the backend is trying to use mmap,
but that no longer works.
* merge_qkv: bias can be required, optional, or mandatory
* merge_qkv: glm4.5moe
* merge_qkv: add command loine argument to enable
* merge_qkv: fix tensor dimensions
* merge_qkv: llama-4
* merge_qkv: qwen3 (dense)
* merge_qkv: simplify build_qwen3moe
* cohere2 - simplify graph building
