In effect this patch applies `__host__ __device__` to a subset of the standard library headers and whatever headers *they* happen to include. While it may happen to work, I'm not at all confident that it does not create interesting issues.

Considering that the patch only works with libc++ anyways, perhaps it's time to make (parts) of libc++ itself usable from CUDA/HIP, instead of hacking around it in the wrappers?

@rsmith Richard, who would be the right person to discuss the standard library changes we may need?
