i965/fs: Define logical typed and untyped surface opcodes.
Each logical variant is largely equivalent to the original opcode but instead of taking a single payload source it expects its arguments separately as individual sources, like: typed_surface_write_logical null, coordinates, source, surface, num_coordinates, num_components This patch defines the opcodes and usual instruction boilerplate, including a placeholder lowering function provided mainly as documentation for their source registers.
