If for some reason kernel is not able to create surface,
when no buffer was provided the function
vmw_svga_winsys_surface_create should return NULL.
This patch fixes the issue where the code was not following the
clean up path in case of error, which used to cause SIGSEGV.

The main goal of this pass to merge temporary registers in order
to reduce the total number of registers and also to produce
optimal TGSI code.
In fact, compilers seem to be confused when temporary variables
are already merged, maybe because it's done too early in the
process.
Skipping the pass, reduce both the register pressure and the code
size, at least for Nouveau and RadeonSI because they have a real
backend compiler.
Found by luck while fixing an issue in the TGSI dead code elimination
pass which affects tex instructions with bindless samplers.

There are 2 major hw changes:
- The address must always point to the address of level 0. GFX9 tiling
modes don't allow binding to a non-0 level.
- 3D must always be bound as 3D, because 2D and 3D use entirely different
tiling modes, and the texture target determines which set of modes is
used.

Shared context support for VAOs was dropped in 0b2750620b.
From the ARB_vertex_array_object spec:
"This extension differs from GL_APPLE_vertex_array_object
in that client memory cannot be accessed through a
non-zero vertex array object. It also differs in that
vertex array objects are explicitly not sharable between
contexts."
Nobody should be using this extension over
ARB_vertex_array_object anymore so just drop it rather than
adding locking back just for VAOs created from these
functions.
For reference the Nvidia blob doesn't expose this extension.

If r300g is the only radeon driver built, the Android build fails to

This is because the path to build libmesa_pipe_radeon was only getting

all radeon drivers. As libmesa_pipe_radeon is not needed for r300g, drop

We need to emit BLEND_STATE, which size is 1 + 2 * nr_draw_buffers
dwords (on gen8+), but the BLEND_STATE struct length is always 17. By
marking it size 1, which is actually the size of the struct minus the
BLEND_STATE_ENTRY's, we can emit a BLEND_STATE of variable number of
entries.
For gen6 and gen7 we set length to 0, since it only contains
BLEND_STATE_ENTRY's, and no other data.
With this change, we also change the code for blorp and anv to emit only
the needed BLEND_STATE_ENTRY's, instead of always emitting 16 dwords on
gen6-7 and 17 dwords on gen8+.
v2:
- Use designated initializers on blorp and remove 0 from
initialization (Jason)
- Default entries to disabled on Vulkan (Jason)
- Rebase code.

Before this commit, when a group with count="0" is found, only one field
is added to the struct representing the instruction. This causes only
one entry to be printed by aubinator, for variable length groups.
With this commit we "detect" that there's a variable length group
(count="0") and store the offset of the last entry added to the struct
when reading the xml. When finally reading the aubdump file, we check
the size of the group and whether we have variable number of elements,
and in that case, reuse the last field to add the remaining elements.

Until now the spilling cost calculation was neglecting the amount of
data read from the register during the spilling cost calculation.
This caused it to make suboptimal decisions in some cases leading to

Currently the NIR backends depend on GLSL IR copy propagation to
fix up the interpolateAt* function params after varying packing
changes the shader input to a global. It's possible copy propagation
might not always do what we need it too, and we also shouldn't
depend on optimisations to do this type of thing for us.
I'm not sure if the same is true for TGSI, but the following
commit should re-enable packing for most cases in a safer way,
so we just disable it everywhere.
