<pre>I found out that the initial uploading using glTexImage2D() falls to
intel_texsubimage_tiled_memcpy() path. I tried disabling special streaming
instructions in intel_tiled_memcpy.c and now I seem to get results from
different cache line(s) than before. Previously it was consistently the same,
now the pixel values correspond to different location in the texture and vary
from run to another.</pre>
