sna: Use Y-tiling for source pixmaps
Y-tiling is slightly faster with RENDER operations, so attempt to
allocate source-only pixmaps using this tiling mode. Actually using
Y-tiling is a delicate balance because it then prevents the use of the
BLT. For instance, enabling Y-tiling by default gives a 30% performance
improvement on the fish-demo (compositing benchmark) at 2560x1440 on
Ironlake but regresses tiger-demo by 2x (spans benchmark).
So experiment with this compromise and allow for changing the default
tiling.
