Now that both GLSL and SPIR-V are adding shared and tcs_patch barriers
(as appropreate) prior to the nir_intrinsic_barrier, we don't need to do
it ourselves in the back-end. This reverts commit
26e950a5de01564e3b5f2148ae994454ae5205fe.

The GLSL barrier() intrinsic does an implicit shared memory barrier in
compute shaders and an implicit TCS patch output barrier in tessellation
control shaders. We'd like NIR's barrier intrinsic to just be a control
flow barrier and not have memory implications. To satisfy this, we need
to add an extra memory barrier in front of each nir_intrinsic_barrier.

As per the Vulkan memory model, the proper translation of GLSL barrier()
is an OpControlBarrier with a scope of Workgroup and semantics of
Acquire, Release, and WorkgroupMemory. Older versions of GLSLang gave
an OpControlBarrier with semantics of None so we need to patch it up on
those versions.

Right now, it's implemented as a no-op for everyone. For most drivers,
it's a switch case in the NIR -> whatever which just breaks. For ir3,
they already have code to delete tessellation barriers so we just add a
case to also delete memory_barrier_tcs_patch.

This re-enables and fixes support for stencil buffer.
It fixes 365 stencil related deqp tests. All tests that use INCR, INCR_WRAR,
DECR and DECR_WRAP as a stencil op still fail, but they also fail with the
blob, so we may ignore that for now.
We still have dEQP-GLES2.functional.depth_stencil_clear.depth_stencil_masked
failing, which is strange because it's the only one out of the
depth_stencil_clear.* set.

It can't be enabled for geometry shaders, for NGG streamout and
for vertex shaders that export the primitive ID. NGG passthrough

Per the semi-recently-released NVIDIA docs, when this bit is not
enabled, then the result for RT[0] will be used. So if e.g. only a
single RT is drawn to and it's not RT[2], the results will not be
visible. Fixes
GTF-GL45.gtf33.GL3Tests.explicit_attrib_location.explicit_attrib_location_pipeline
which was failing due to a frag shader outputting only to location=2.

This corresponds to gl_PrimitiveID and gl_Layer. When both of these are
stored in a single AST.64 or AST.128 operation, then it appears as
though the whole store fails. Fixes the recently extended
glsl-1.50-transform-feedback-builtins piglit, and also
gtf30.GL3Tests.transform_feedback.transform_feedback_builtins.
The issue was reproduced on GM107 and GP108 but not GK208 nor GK104.

Perhaps in a future implementation, such events could be passed back to
the driver, or queried directly. However for now, this is required for
GL 4.3 robustness contexts.

The fix was found by Karol Herbst a long time ago, but it was unclear
why it helped or if it would create additional problems. This change
adds a comment that explains what's going on, and in the process also
normalizes the nv50 implementation to match.
The coordinates which are fed to gl_Position map directly to pixel
coordinates, since the viewport transform is disabled. If the
framebuffer is MSAA, then that doesn't affect the pixel coordinates at
all, it's just that each pixel has multiple samples.
Note that this makes it really clear that this approach is inappropriate
for EXT_framebuffer_multisample_blit_scaled, and also the 3d path will
fail terribly for direct copies. Thankfully the 2d path normally takes
care of this.
Fixes KHR-GL43.packed_depth_stencil.blit.depth32f_stencil8 as well as
scaling issues in a number of EXT_framebuffer_multisample-related piglit
tests (although they continue to fail due to inaccuracies).

lima doesn't support alpha test, flat shading, two-sided color nor
