Profiler: Support for memory snapshots and timelines

[rkistner]

Is support planned for memory snapshots and/or timelines? (Memory snapshots are listed in the interface, but never completes for me)

Safari's dev tools are constantly crashing for me, and debugging memory usage is the one feature that I'd gladly pay for.

@rkistner Not at the moment as the memory/tracing formats between Chrome and Webkit are quite different, so this would require some significant work to reverse engineer that.

I would also highly appreciate memory snapshots. With Safari on iOS being so picky about memory, having a look into the current objects is invaluable.
