Hi Alex,

> Add a pass that renames everything with metasyntatic names. This works well after using bugpoint to reduce the confusion presented by the original names, which no longer mean what they used to.

I'm sure aliases and globals are feeling sad because they don't get funky names
too.  Any reason why not?
