Comment at: mlir/include/mlir/Dialect/GPU/GPUOps.td:487
+    incovation of the `gpu.func`.
+    As `gpu.launch` does not return any values, it is expected that a
+    corresponding `gpu.return` also has no operands.

But they are not. When used inside of a launch, it cannot have operands. I could maybe state that gpu.launch is considered equivalent to a void function? I found it surprising that launch now has a return (as opposed to the terminator). That moves it closer to a function where it should feel more like a loop. WDYT about adding the terminator op back or is that too many operations?
