    intel: Avoid trying to do blits to Y tiled regions.

    This is somewhat nasty, but we need to do Y-tiled depth for FBO support.
    May help with corruption and hangs since enabling texture tiling, and
    since switching depth textures to Y tiled.

    Fixes piglit depthtex.c on 965.

Reproduce steps:
2. glean -r result -o -t depthStencil

Can't reproduce on GM45.  Could you retest with Mesa master?

Yes. It now works well with the newest code of Nov.1. So verified.
