guansong added a project: OpenMP.

Enable the device side debug messages at compile time, use env var to control at runtime.

To achieve this, an environment data block is passed to the device lib when it is loaded.

By default, the message is off, to enable it, a user need to set LIBOMPDEVICE_DEBUG=1.
