panfrost: Add base of OpenCL C infrastructure

Browse Source 
This allows compiling CL shaders into a single SPIR-V library per arch,
NIR call bindings for each functions and precompilled binaries for each
entrypoints.

We are only going to support Bifrost and Valhall for this.

@@ -47,13 +47,18 @@ controllers paired with Mali GPUs. If your board with a Panfrost supported GPU
has a display controller with mainline Linux support not supported by kmsro,
it's easy to add support, see the commit ``cff7de4bb597e9`` as an example.
LLVM is *not* required by Panfrost's compilers. LLVM support in Mesa can
safely be disabled for most OpenGL ES users with Panfrost.
Build like ``meson . build/ -Dvulkan-drivers=panfrost
-Dgallium-drivers=panfrost -Dllvm=disabled`` for a build directory
-Dgallium-drivers=panfrost`` for a build directory
``build``.
LLVM is required by Panfrost's compilers at build time.
In case of cross compilation without LLVM,
you can build and install the required tools on the host (with LLVM installed) with
``meson . build-host/ -Dvulkan-drivers=panfrost -Dgallium-drivers=panfrost
-Dmesa-clc=enabled -Dinstall-mesa-clc=true -Dprecomp-compiler=enabled -Dinstall-precomp-compiler=true``
and then use ``-Dmesa-clc=system -Dprecomp-compiler=system`` on the cross compile side.
For general information on building Mesa, read :doc:`the install documentation
<../install>`.
