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

Actually, this isn't enough.  It works fine for std::complex, but it screws with our existing std math business, because some of the host functions that we're trying to override are constexpr, and now they're treated as constexpr host-device.
