This patch broke the DRI driver on older gen4/4.5/5 Intel HW, see bugs
1735594 and 1741447

I've backported five commits from upstream to fix this properly, at
least this backport doesn't crash on my HW anymore.

Bug description:
  [Impact]

  Corruption is seen on windowed 3D apps running on dGPU

  [Test case]

  Get a certain Intel/AMD hybrid machine, run 'DRI_PRIME=1 glxgears',
  see how the window has corrupted gfx.

  The fix is to patch Intel i965_dri driver.

  [Regression potential]

  There could be a slight loss of performance, but corruption free
  behaviour.
