Expose some weaknesses in the generator: we don't always forbid
the generation of structs that contain multiple members that map
to the same C name. This has already been marked FIXME in
qapi.py, but having more tests will make sure future patches
produce desired behavior.
Some of these tests will be deleted later, and a positive test
added to qapi-schema-test.json in its place, when the code is
reworked so that the collision no longer occurs.
