[PATCH] D18219: Add -cuda-relaxed-constexpr, which lets CUDA device code call constexpr functions.

Abandoning this for now -- it is a maze of twisty passages all alike.  Some std math functions are constexpr, and making them host+device affects all our existing math overloads in fun and exciting ways.

We may need this at some point, but for now I'm going to try something more finely targeted specifically at std::complex.
