<pre>It took me half a day to bisect it to Anuj's series, ending in:
i965: Don't use fast copy blit in case of logical operations other than GL_COPY
XY_FAST_COPY_BLT command doesn't have a field for raster operation. So, fall
back to using XY_SRC_COPY_BLT to handle those cases.
Fixes piglit test gl-1.1-xor-copypixels when fast copy blit is enabled
for all tiling formats.

The failures are not easy to reproduce, and it can take several *full* runs to
see them. I'm confident that it is from these commits, because I looked at
Anuj's pre-commit developer builds, and also found the regressions in those
results.</pre>
