Title: Adding a 'health' tracker for warning the user about bad instrumentation.

This adds a HealthInfo type that can be used to generate warnings and a 'bad' bit about a trace. This is used by the UI to show a warning string and present the user with the warnings and links for more information on github.

It also adds a small now() benchmark, however it's not plumbed through yet.
