Bug detailed description:
Start the gnome with the compiz, the display is messed. So long as we killed the compiz, the display returns to normal.
There isn't the issue on the Ironlake platform.

i965: Avoid using float type for raw moves, to work around SNB issue.
The SNB alt-mode math does the denorm and inf reduction even for a
"raw MOV" like we do for g0 message header setup, where we are moving
values that aren't actually floats. Just use UD type, where raw MOVs
really are raw MOVs.
Fixes glxgears since c52adfc2e1d130effea940e75690897eb5d3ceaa, but no
piglit tests had regressed(!)
Reopen if you still had issue.
The issue is gone,so verified it.
