This is a WIP patch to show one way of implementing math support (and
support for `new`, `algorithm`, ...) in OpenMP target regions by piggy
backing on the CUDA implementation. All CUDA "code" should be in
`omp begin/end declare variant match(device={arch(nvptx)})` at the end
of the day while the "host" code is not.
