[Mesa-dev] [PATCH v3 16/19] nir: add load_kernel_param

[Karol Herbst]

OpenCL kernels have parameters (see pipe_grid_info::input), and so we
need a way to access them.

The offset source is the offset of the parameter to load in the kernel input
buffer.

v2: improve commit message
    remove BASE
    split lower_io changes into separate commit
