[PATCH] D26196: Add support for non-zero null pointer for C and OpenCL

Hi John,

It seems the casting from a pointer to different address space is not affected by this change. When a null pointer is casted to different address space, it is casted the same way as an ordinary pointer, e.g. by addrspacecast.

I think this patch covers most of the changes that is needed for supporting non-zero null pointer in C and OpenCL. Is there anything else missing?

Thanks.
