[LIT] Add option to print summary of tests that pass.

[EricWF]

Summary

I'm currently working on running the libc++ tests in different configurations. It's often quite helpful print a summary of the tests that pass alongside the tests that fail. This adds an option called --show-passing to do that. It's off by default.

Why wouldn't you just run without -s if you want all that output? Just for
the grouping?

Precisely, I want the grouping because 90% of the tests I'm looking at are failing. So the passing tests get lost in all of the failure messages. I really just want a short list of tests that are passing.

Abandoning. There seems to be no consensus for change.
