Simple unions are simpler than flat unions in the schema, but more
complicated in C and on the QMP wire: there's extra indirection in C
and extra nesting on the wire, both pointless.  They're best avoided
in new code.

But we can do more: we can flatten the simple unions that aren't used
in QMP.

In the longer run, I'd love to get rid of simple unions entirely, and
reduce the notational overhead of flat unions in the schema.
