meson: Add a "prefer_iris" build option

Enabling this option makes Intel Gen8-11 hardware load the 'iris'
driver by default instead of the older 'i965' driver.

Regardless of how this option is set, users can still override which
driver the loader selects via two methods.  The first is to create a
~/.drirc or /etc/drirc file with the following snippet:

   <driconf>
     <device driver="loader" kernel_driver="i915">
       <option name="dri_driver" value="i965" />
     </device>
   </driconf>

The other option is to set an environment variable:

   export MESA_LOADER_DRIVER_OVERRIDE=i965

For now, "prefer_iris" defaults to i965 (the historical choice).
A separate future patch will change the default driver to iris.

drirc: Set vs_position_always_invariant for Shadow of Mordor on Intel

When drawing the main character in Shadow of Mordor, the game appears
to draw Talion with one vertex shader, and the Wraith with another.
If the compiler optimizes those in different ways which lead to slight
imprecisions, then the resulting positions may not line up, leading to
Z-fighting occurring as the game decides which of the two are in front.

brw_nir_opt_peephole_ffma looks at usages of multiply adds across the
entire shader, and may make different decisions between the two, leading
to such imprecisions and Z-fighting.  This started happening recently
after a NIR change to eliminate unnecessary MOVs (7025dbe7), but that
change simply exposed the existing problem.

Improves performance on Skylake GT4e by 1.22945% +/- 0.398672% (n=3),
likely due to the fixed rendering.

driconf, glsl: Add a vs_position_always_invariant option

Many applications use multi-pass rendering and require their vertex
shader position to be computed the same way each time.  Optimizations
may consider, say, fusing a multiply-add based on global usage of an
expression in a shader.  But a second shader with the same expression
may have different code, causing that optimization to make the other
choice the second time around.

The correct solution is for applications to mark their VS outputs
'invariant', indicating they need multiple shaders to compute that
output in the same manner.  However, most applications fail to do so.

So, we add a new driconf option - vs_position_always_invariant - which
forces the gl_Position output in vertex shaders to be marked invariant.

v3d: fix indirect BO allocation for uniforms

We were always ensuring a minimum size of 4 bytes for uniforms
for the case where we don't have any, to account for hardware pre-fetching
of the uniform stream, however, pre-fetching could also lead to to out
of bounds reads when have read the last uniform in the stream, so we
probably want to have the extra 4 bytes to prevent the kernel from
observing invalid memory accesses when the uniform stream sits right at
