Pierre-Eric Pelloux-Prayer dc293ffe50 radeonsi: fallback to util_blitter_draw_rectangle
The blitter VS expects coords to fit in a signed int16. When this
is not the case, use util_blitter_draw_rectangle instead.

Since util_blitter_draw_rectangle sets vertex elements, we need
to make sure they're properly restored.

The alternative to this fallback would be to pass coordinates
unpacked (so 4 SGPRs instead of 2), but this doesn't fix the
fbo-blit-check-limits test because of uv interpolation precision
issue.
Using 2 triangles instead of a rectangle + disabling
window_space_position helps but then this breaks some GLES3 tests,
like dEQP-GLES3.functional.fbo.blit.rect.nearest_consistency_mag_reverse_src_x
(which doesn't pass either if u_blitter is used for all cases).

Using a single triangle covering the whole rectangles fixes all
cases but it then requires to setup scissors to not write too
much pixels...
So, instead of adding so much complexity, let's use u_blitter
for the "large coordinates" fallback, and keep the rectangle blit
for the other cases.

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

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

.. code-block:: sh

  $ meson setup build
  $ ninja -C build/
  $ sudo ninja -C build/ install
