Fix test failures after r335306 due to the pipeline changing.

This wasn't obvious for the author to fix because this is the first
pipeline use of the magic utility to get function analyses within
a module pass in the lagecy pass manager. Turns out that has a bug which
prevents dumping the structure of the pipeline and shows up as an
unnamed pass.

I've just left a FIXME for that as it doesn't seem likely worth fixing
and certainly shouldn't hold up getting the bots green.
