We don't need to use fixed-size pixel_t types and put the tiling loop in a macro in order to get good codegen for this. Replacing the fixed-size types with memcpy/__builtin_assume_aligned, the compiler is still able to generate multi-word load/store instructions. Without the fixed-size types, the only advantage of putting this in a macro is to ensure the code is specialized on size/is_store/shift, but we can get the same specialization by making the functions ALWAYS_INLINE. Measured performance in VK_EXT_host_image_copy benchmraks is unchanged, and generated assembly looks effectively identical to the previous version.
