AMDGPU: Add pass to lower OpenCL image and sampler arguments.

Browse Source 
The pass adds new kernel arguments for image attributes, and
resolves calls to dummy attribute and resource id getter functions.

Patch by: Zoltan Gilian

///
/// 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.
