trace-cmd: Add option to group like comms for profile

When profiling large applications that have multiple children we really want to
see the profile of the app all together.  Add a --by-comm option to accomplish
this for profile.  This merges all the events for like comms into one big chunk
so we can easily see what a giant app is doing, such as HHVM.  Thanks,
