This patch changes the way the reproducer is initialized. Rather than making changes at run time we now do everything at initialization time. To make this happen we had to introduce initializer options and their SB variant. This allows us to tell the initializer that we're running in reproducer capture/replay mode. Because of this change we also had to alter our testing strategy. We cannot reinitialize LLDB when using the dotest infrastructure. Instead we use lit and invoke two instances of the driver. Another consequence is that we can no longer enable capture or replay through commands. This was bound to go away form the beginning, but I had something in mind where you could enable/disable specific providers. However this seems like it adds very little value right now so the corresponding commands were removed. Finally this change also means you now have to control this through the driver, for which I replaced --reproducer with --capture and --replay to differentiate between the two modes.
