This pass resolves calls to OpenCL image attribute, image resource ID and sampler resource ID getter functions.
Image attributes (size and format) are expected to be passed to the kernel as kernel arguments immediately following the image argument itself, therefore this pass adds image size and format arguments to the kernel functions in the module. The kernel functions with image arguments are re-created using the new signature. The new arguments are added to the kernel metadata with kernel_arg_type set to "image_size" or "image_format". Note: this pass may invalidate pointers to functions.
Resource IDs of read-only images, write-only images and samplers are defined to be their index among the kernel arguments of the same type and access qualifier.
