vulkan: use map for mul_mm shapes
cleanup
fix indentation
fix cm2 and shmem init
fix cm2 spec constants
fix cm2 bindings
consolidate shmem tables and reduce size by type spec constant
fix compiler warning
fix missing Q2_0 type
fix unused warning when integer dot glslc support is missing
use minimal shmem size 8 instead of 1 to workaround cm2 compiler bug
fix missing Q2_0 type in cm2 matmul
fix types
* ggml: fix backend split scheduler race condition
splits without input were running concurrently with other splits, while potentially reusing memory the other split is accessing
* only sync when split has no inputs
* llama: add new default load-mode auto which picks mmap unless a non-Metal iGPU is used
* Update ggml/src/ggml-hexagon/ggml-hexagon.cpp

* set mmap_support to false on OpenCL backend
* fix order of load modes
* use -1 for auto
* resolve load mode auto earlier to correctly pick gpu host or cpu memory
* add load mode auto to llama-bench
* bump virtgpu api version, regenerate docs
