Bad codegen for HEAD verb

[brjohnsn]

Given the following resource definition, the code generated for the Go client does not compile and the code generated for the server returns a message body.

//
// Determines whether record exists for a given ID.
//
resource Any HEAD "/status/{id}" {
  Int64 id;
  expected OK; // Matching entry found
  exceptions {
    ResourceError NOT_FOUND; // No entry found
  }
}

The generated server code can be forced to return no message body if the expected result is changed to NO_CONTENT. However the client code still does not compile in this case. The only way to get generated code with behavior similar to that expected with the HEAD verb is to change the verb to GET and the expected result to NO_CONTENT.
