  Log Message:
  -----------
  [OpenMP] Delay more diagnostics of potentially non-emitted code

Even code in target and declare target regions might not be emitted.
With this patch we delay more diagnostics and use laziness and linkage
to determine if a function is emitted (for the device). Note that we
still eagerly emit diagnostics for target regions, unfortunately, see
the TODO for the reason.

This hopefully fixes PR48933.
