[[cl::max_size]] does not work for all specified pointer/ref types

[ex-rzr]

OpenCL C++ specification:

This attribute can be provided with a kernel argument of type constant_ptr<T>, constant<T>*, constant<T>&, local_ptr<T>, local<T>*, local<T>&.

#include <opencl_memory>

template <typename T>
struct local_ptr_test
{
    __local T* ptr;
};

typedef local_ptr_test<int> local_int_test;

kernel void foo0([[cl::max_size(1)]] local_ptr_test<int> arg) { }


kernel void foo1([[cl::max_size(1)]] cl::local_ptr<int> arg) { }
kernel void foo2([[cl::max_size(1)]] cl::local<int>* arg) { }
kernel void foo3([[cl::max_size(1)]] cl::local<int>& arg) { }

kernel void foo4([[cl::max_size(1)]] cl::constant_ptr<int> arg) { }
kernel void foo5([[cl::max_size(1)]] cl::constant<int>* arg) { }
kernel void foo6([[cl::max_size(1)]] cl::constant<int>& arg) { }

(foo0 is a kernel from https://github.com/KhronosGroup/SPIR/blob/spirv-1.1/test/OpenCL/OpenCL22/attributes/TestBasicAttributes_max_size.cl)

I.e. the attribute works with cl::local<int>* and cl::constant<int>*.

(Also there is a typo (paremeters) in error messages)
