[PATCH] D31856: Headers: Make the type of SIZE_MAX the same as size_t

Thanks for the review.  `__SIZE_MAX__` makes sense to me; and better even if not for the `#if` requirement.  I'll do that for both `SIZE_MAX` and `PTRDIFF_MAX` when I get a chance.

This testcase has a `#define int a` to confirm that we get `intmax_t` from our token pasting instead of `amax_t`.  `unsigned a` looks bogus, but I figure such a user is getting what they asked for.
