  Log Message:
  -----------
  [OpenMP] Initial support for std::complex in target regions

This simply follows the scheme we have for other wrappers. It resolves
the current link problem, e.g., `__muldc3 not found`, when std::complex
operations are used on a device.

This will not allow complex make math function calls to work properly,
e.g., sin, but that is more complex (pan intended) anyway.
