[Reproducer] Add reproducer dump command.

Browse Source 
This adds a reproducer dump commands which makes it possible to inspect
a reproducer from inside LLDB. Currently it supports the Files, Commands
and Version providers. I'm planning to add support for the GDB Remote
provider in a follow-up patch.
