[ANNOUNCE] xf86-video-intel 2.20.14

[Chris Wilson]

The highlight of this release is gen4, from 965g to gm45. Quite an old
bug surfaced in the shader assembly, sparking a chance to review a few
design choices within that backend and experiment on fresh ways to
workaround the remaining issues.

 * Avoid using inplace XOR'ed uploads for very large buffers
   https://bugs.freedesktop.org/show_bug.cgi?id=57031

 * Fix the gen4/5 opacity shader
   https://bugs.freedesktop.org/show_bug.cgi?id=57054

 * Queue a pending vblank request after flip completion
   https://bugs.freedesktop.org/show_bug.cgi?id=56423

 * Avoid migrating an uninitialised pixmap for use as a render source
   https://bugs.freedesktop.org/show_bug.cgi?id=47597

 * Improve handing of texture fallbacks for 830/845.
