We need to extend the coherent memory tracker to deal with swiftshader more easily.

Swiftshader writes to coherent memory from the CPU (Because it is a CPU implementation of the driver).
We will catch those writes, and treat them as application writes, this will give us odd behavior.

Instead, we should either a) detect CPU implementations of the driver, and turn off the coherent memory tracker, or better yet, detect when these calls are coming from within the driver (if possible). Likeley the first for now.
