freedreno/ir3: fix issue with emit_tex()

For various tex fetch instructions, coord's get fixed up in different
ways.  But modifying the array returned from get_src() has side-effects
if the same SSA src is used again.. the later instruction will see the

i965: Change 8x multisample positions

There are no standard sample positions defined in OpenGL and OpenGL
ES specs. Implementations have the freedom to pick the positions
which give plausible results. But the Vulkan 1.0 spec does define
standard sample positions for different sample counts. Defined
positions in Vulkan for all the sample counts except 8X match with
the positions we set in i965. We have an upcoming plan to share the
blorp code between OpenGL and Vulkan driver in near future. Keeping
the 8X sample positions same on both the drivers will help us move
in that direction.

Here is an argument by Neil Roberts (from commit 20250e85) against
any advantage of current 8X sample positions over the new ones:

"The comment above for the 8x sample positions says that the hardware
implements centroid interpolation by picking the centre-most sample
that is inside the primitive. That implies that it might be worthwhile
to pick a pattern that includes 0.5,0.5. However by experimentation
this doesn't seem to actually be the case. With the sample positions
in this patch, if I modify the piglit test below so that it instead
reports the centroid position, it reports 0.492188,0.421875 which
doesn't match any of the positions. If I modify the sample positions
so that they include one at exactly 0.5,0.5 it doesn't help and it
reports another position which is even further from the center for
some reason.

arb_gpu_shader5-interpolateAtSample-different

Kenneth Graunke experimented with some other patterns that have a
higher standard deviation but I think after some discussion it was
decided that it would be better to pick the same pattern as the other
graphics API in case there are games that rely on this pattern."

New languages only allow outputs to be qualified as "invariant"

varyings (because no input can have that qualifier).

radeonsi: enable multi-draw related pipe caps

This enables GL_shader_draw_parameters and GL_ARB_indirect_parameters as well
as a properly accelerated implementation of GL_ARB_multi_draw_indirect.

Enabling the feature requires a sufficiently uptodate firmware -- those have
already been released a long time ago, although this does mean that the
feature only works with the amdgpu kernel module, since the radeon module
doesn't have a way to query the firmware version.

nir: Always print non-identity swizzles.

Previously we would not print a swizzle on ssa_52 when only its .x
component is used (as seen in the definition of ssa_53):

   vec3 ssa_52 = fadd ssa_51, ssa_51

   vec1 ssa_54 = flog2 ssa_52.y
   vec1 ssa_55 = flog2 ssa_52.z

But this makes the interpretation of the RHS of the definition difficult
to understand and dependent on the size of the LHS. Just print swizzles
when they are not the identity swizzle, so the previous example is now
printed as:

   vec3 ssa_52 = fadd ssa_51.xyz, ssa_51.xyz
   vec1 ssa_53 = flog2 ssa_52.x
   vec1 ssa_54 = flog2 ssa_52.y
