This prevents some additional optimizations that would change the
original result. This includes things like (b < a && b < c) => b <
min(a, c) and !(a < b) => b >= a. Both of these optimizations were
specifically observed in the piglit tests added in piglit!160.
This was discovered while investigating
https://gitlab.freedesktop.org/mesa/mesa/issues/1958. However, the
problem in that issue was Chrome or Angle is replacing calls to isnan()
with some stuff that we (correctly) optimize to false. If they had left
the calls to isnan() alone, everything would have just worked.
No shader-db changes on any Intel platform.
I also tried marking the comparison generated by the isnan() function
precise. The precise marker "infects" every computation involved in
calculating the parameter to the isnan() function, and this severely
hurt all of the (few) shaders in shader-db that use isnan().
I also considered adding a new ir_unop_isnan opcode that would implement
the functionality. During GLSL IR-to-NIR translation, the resulting
comparison operation would be marked exact (and the samething would need
to happen in SPIR-V translation).
This approach taken by this patch seemed easier, but we may want to do
the ir_unop_isnan thing anyway.

We would like to pack not just xyzw swizzles but also efgh swizzles.
This should work for vec4/16-bit. More work will be needed to pack
swizzles for vec8/16-bit and even more work for 8-bit, of course.

Midgard prefetches instructions based on tag (ALU, LD/ST, texture *
size). To do so, the shader descriptor specifies the tag of the first
instruction, all instructions specify the tag of the next linear
instruction is, and all branches explicitly specify the tag of the
branch target.
If you mess this up, you get an INSTR_TYPE_MISMATCH, which unambiguously
refers to this problem, but it's still annoying to try to work out all
the branch targets in your head to debug.
Instead, let's track the tags of various blocks over time, so we can
automatically validate tags of branch targets, to make
INSTR_TYPE_MISMATCH issues immediately obvious in a disassembly.

When importing a dmabuf with a specified tiling, the dmabuf user
should always try to set the tiling mode because: 1) the exporter
can set tiling AFTER exporting/importing. 2) a dmabuf could be
exported from a kernel driver other than i915, in this case the
dmabuf user and exporter need to set tiling separately.
This patch fixes a problem when running vkmark under weston with
iris on ICL, it crashed to console with the following assert. i965
doesn't have this problem as it always tries to set the specified
tiling mode.

In 2ca0d913ea, we began updating cso_fb->layers to the actual layer
count, rather than 0. This fixed cases where we were setting "Force
Zero RTA Index Enable" even when doing layered rendering. Sadly, it
also broke the check entirely: cso_fb->layers is now 1 for non-layered
cases, but the Force Zero RTA Index check was still comparing for 0.

Python has the identity operator `is`, and the equality operator `==`.
Using `is` with strings sometimes works in CPython due to optimizations

This is incorrect, because polygonMode only applies if the final
primitive type is a polygon; polygonMode doesn't apply to
line-primitives as the comment suggests.
The Vulkan 1.1 spec, section 26.11, "Polygons" defines that polygons are
separate from points and line segments:
" A polygon results from the decomposition of a triangle strip, triangle
fan or a series of independent triangles. Like points and line segments,
polygon rasterization is controlled by several variables in the
VkPipelineRasterizationStateCreateInfo structure. "
Further, section 26.11.2, "Polygon Mode", only define polygonMode to
apply to polygons:
" Possible values of the VkPipelineRasterizationStateCreateInfo::polygonMode
property of the currently active pipeline, specifying the method of
rasterization for polygons, are: "
This seems to clearly define that polygonMode doesn't apply to points
and lines, so let's make sure that we don't early out with the wrong
value.

We want symmetry between loads and stores, so we add a dummy source. So

load is simply a move. That means it has a swizzle that acts as a
