cc: Fix tile manager queues perftests to use number of layers.
I made a bit of a blunder when writing the tile manager queues perftests
and made them use a variable number of tilings, instead of layers.
The important thing for us to test here is how the system behaves with
multiple layers. Multiple tilings case is tested at the tiling level
iterator level.
This patch fixes up all of this.
NOTE TO PERF SHERIFFS
=====================
Please disregard any performance changes in the tile manager perftests
as a result of this patch. This changes fundamentally what the
perftests are measuring.
