Chris Wilson 66d5f092d4 igt/gem_render_tiled_blits: Speed up by using the GPU to detile ...

Avoid accessing via the slow GTT to read back and compare the contents
of each bo against expected results. It is much faster, on llc at least,
to detile using the GPU and then copy to system memory for the compare.

Before:

IVB: time sudo ./gem_render_tiled_blits
IGT-Version: 1.6-ge46ff3f (x86_64) (Linux: 3.15.0-rc3+ x86_64)

Using pread:

IVB: time sudo ./gem_render_tiled_blits
IGT-Version: 1.6-ge46ff3f (x86_64) (Linux: 3.15.0-rc3+ x86_64)

real	0m14.717s
user	0m3.699s
sys	0m3.192s

Using snoop:

IVB: time sudo ./gem_render_tiled_blits
IGT-Version: 1.6-ge46ff3f (x86_64) (Linux: 3.15.0-rc3+ x86_64)
Using 3072 1MiB buffers

real	0m13.774s
user	0m3.900s
sys	0m2.089s

PNV: time sudo ./gem_render_tiled_blits
IGT-Version: 1.6-g8556f8a (i686) (Linux: 3.15.0-rc2+ i686)
Using 768 1MiB buffers

real	0m20.831s
user	0m4.384s
sys	0m5.032s

So roughly 10-30x faster depending on platform.
