* Adding fused mul+multi_add + CPU implementation
* fused mul+multi_add: command line argument to disable it
* Faster tensor name formatting
We gain ~1% for Ling-mini-2.0 when running on CUDA.

* Fuse add+add+fused_rms
* Try this
* Macro to easily enable/disable fusion
* Various:
* Check that all tensors involved are on the same device before applying fusion
* Fuse sigmoid+scale+sum_rows+div
* Fix the fused bailingmoe2 experts selection
The issue there was that the bias was not per row, but per
expert group, so only the first n_per_group biases were used
for al experts.

* Combine all calls to llm_build_norm to a single line
so more easily check what kind of arguments are being passed
by simply using grep.
* Combine add + fused_rms_norm
For many models this happens at each layer: the result of the
layer is added to the ayer input, which then becomes the input
to the next layer, which then is typically normalized via
fused_rms_norm.

* Do not allocate KV cache for unused layers
* Do not apply experts weight scale if it is 1

* Fuse sigmoid+add+grouped_topk+get_rows (CPU)
* Fix CPU + CUDA
but CUDA is somehow not 100% correct as I get a slightly different
PPL (lower!)
* Minor
* Fuse sigmoid+add+topk+get_rows (CUDA)
* Fuse sigmoid+add+topk+get_rows (CPU)
* Fuse topk+view+get_rows+reshape+softmax (CPU)
* Fuse topk+view+get_rows+reshape+softmax (CUDA)
* cpu: turn off the openai topk fusing for now
Something is not right and I don't see the bug.
On the CPU one doesn't gain much if anything, so not a big loss.
* Also fuse sum_rows and div

* Conditionally write moe_shared_expert_intermediate_size
Ling-1T config.json does *not* have `moe_shared_expert_intermediate_size`.
Ling-flash-2.0a *does* have it.
This small patch just makes the gguf_writer conditionally detect as
needed.
* Fix Ling-1T missing moe_shared_expert_intermediate_size
Thanks CISC for the proper patch to include the needed values!
* Better argsort (CPU)
* Attemt at grouped topk
* This seems to do the trick for grouped experts routing
* Cleanup
* Trying to merge, something is not right
* Working merged grouped top_k (CPU)
* Add command line option to enable grouped expert routing
* Add grouped expert routing option to llama-bench

* Parallelize mask
We see non-negligible PP gains for long contexts.
More importantly, the strange drop in performance
observed for GPT-OSS for context >= 32k tokens is gone.
* Whith FA on, create mask as f16 directly
* WIP
* Reduce KQ mask padding to 16
Why was it 64 in the first place?
I don't observe any issues, while TG performance
for long contexts improves by 2-4%.

* llama_model and llama_hparams
* llama_build_context
Surprisingly small reduction in llama.cpp compile time given
the reduction in LOCs (22k -> 14k)
* LLM_TN
llama.cpp compilation: 50 s -> 33 s
* llama_quantize
* arch names
* All graph building is now in llm-build-context.cpp
* hparams loading
llama.cpp is now just 9300 LOC, but still takes 32 seconds to compile.
* We are now at 6 seconds to build the src folder
* load -> create
We are not actually loading the tensors, but just creating them.
