Yeah, I'm looking through the code and it looks like we're always just
using the function id when we should be using the symbol name. Let me
land a patch to fix this.

You can try this manually by using the `llvm-xray extract -symbolize`
tool to get a YAML file that maps the function id's to symbols, but
that's a roundabout way of doing it. Ideally the graph-diff tool
should just do it.
