[XRay] A tool for Comparing xray function call graphs

Summary:
This is a tool for comparing the function graphs produced by the
llvm-xray graph too. It takes the form of a new subcommand of the
llvm-xray tool 'graph-diff'.

This initial version of the patch is very rough, but it is close to
feature complete.

Depends on D29363
