  Log Message:
  -----------
  Add 'gpu.terminator' operation.

Summary:
The 'gpu.terminator' operation is used as the terminator for the
regions of gpu.launch. This is to disambugaute them from the
return operation on 'gpu.func' functions.

This is a breaking change and users of the gpu dialect will need
to adapt their code when producting 'gpu.launch' operations.
