Demonstator for problem

I can create constexpr constants without an address space qualifier, but if I
try to create a static constexpr class members (which are essentially just
constexpr constants), clang complains:

error: program scope variable must reside in global or constant address space

The attached test case demonstates the problem.

CUDA has special treatment to allow such constexpr static members. I didn't
read something in the OpenCL spec about this, but out of convenience and
compatibility, I think it should be supported as well.
