Can you split this change out since you had another patch for it?

[Ankur Verma, 2015/06/04 15:25:08]

I could not understand completely (this being my first chromium bug).

This change bring us back to the original patch.
1. First, i had deleted test_now_source.* files and converted this to use
SimpleTestTickClock.
2. Then, i had added the num_now_calls_ functionality to it.
3. Then, i removed the num_now_calls_functionality from it. Hence back to 1.

Would you like me to restore test_now_source.* files and remove this change. And
then remove test_now_source.* in a separate patch?

On rebasing for patch set 8, i realised that
https://codereview.chromium.org/1163143002
performed a separate cleanup on this.

I've now replaced cc::TestNowSource with base::SimpleTestTickClock on top of
that.
