Kenneth Graunke d832209a78 blorp: Fix compute-blits for rectangles not aligned to the workgroup
When dispatching compute shaders to do a blit, our destination rectangle
may not line up perfectly with the workgroup size.  For example, we may
round the left x0 coordinate down to a multiple of the workgroup width,
and the right x1 coordinate up to the next multiple of the workgroup
width.  Similarly for y0/y1 and workgroup height.  This means that we
may dispatch additional invocations which should not actually do any
blitting.  We need to set key->uses_kill to bounds check and drop those.

Caught by Piglit's arb_copy_image-simple when forcing iris to perform
resource_copy_region via BLOCS and running with INTEL_DEBUG=norbc on
Icelake.

Source
------

This repository lives at https://gitlab.freedesktop.org/mesa/mesa.
Other repositories are likely forks, and code found there is not supported.


Build & install
---------------

You can find more information in our documentation (`docs/install.rst
<https://mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.rst <https://mesa3d.org/meson.html>`_):

.. code-block:: sh

  $ mkdir build
  $ cd build
  $ meson ..
  $ sudo ninja install


Support
-------

Many Mesa devs hang on IRC; if you're not sure which channel is
appropriate, you should ask your question on `OFTC's #dri-devel
<irc://irc.oftc.net/dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
