+/// OpenCL v2.0, s6.13.17.1 - Check that sizes are provided for all
----------------
I think the problem is that in C99 there are implicit casts among integer
types, therefore making this check more restrictive would imply the cast has to
be done explicitly instead.
Thus, this would have to be modified as follows:
enqueue_kernel(..., 64); -> enqueue_kernel(..., (uint)64); or
enqueue_kernel(..., 64U);
which in my opinion is undesirable and also a bit unexpected because by analogy
to C99 you can compile the following successfully:
void g(unsigned);
void f() {
char i;
g(i);
}
I have added a check for a size however not to be larger than 32 bits and
handled type cast in CodeGen. The test cases are added too.
What's your opinion about it?

----------------
This error is when we can't deduce exactly which overload is meant to be and we
are giving more general error (like it's ambiguous). You can see some examples
in tests. We could of course go further and specify possible candidates, but it
would complicate the story even more.
