Well, even if regularly done that way, it's not technically quite right:
I'm not modifying "GOMP_OFFLOAD_get_name" et al., but instead I'm adding
them (modifying the "top level" scope). But, I changed that anyway.

ACK.

Ugly, but I guess we still have this 80 columns limit... ;-)

Thanks for the review; committed to trunk in r245062:
