We had some pointless differences in the generated code for visit, command marshalling, and events; unifying them makes it easier for future patches to consolidate to common helper functions. This is one patch of a series to clean up these differences. This patch adjusts gen_visit_union() to use the same indentation as other functions, namely, by jumping early to the error label if the object was not set rather than placing the rest of the body inside an if for when it is set. No change in semantics to the generated code.
