It looks as if the structure fields array is fully initialized below,
but in fact at least gcc in debug builds will not actually overwrite

base_vertex will be zero for non-indexed calls and in that case we
need vertex_id to be offset by the ‘first’ parameter instead. That is
what we get with first_vertex. This is true for both GL and Vulkan.
The freedreno driver is also setting vertex_id_zero_based on
nir_options. In order to avoid breakage this patch switches the
relevant code to handle SYSTEM_VALUE_FIRST_VERTEX so that it can
retain the same behavior.
v2: change a3xx/fd3_emit.c and a4xx/fd4_emit.c from
SYSTEM_VALUE_BASE_VERTEX to SYSTEM_VALUE_FIRST_VERTEX (Kenneth).

The base vertex in Vulkan is different from GL in that for non-indexed
primitives the value is taken from the firstVertex parameter instead
of being set to zero. This coincides with the new SYSTEM_VALUE_FIRST_VERTEX
instead of BASE_VERTEX.
v2 (idr): Add comment describing why SYSTEM_VALUE_FIRST_VERTEX is used
for SpvBuiltInBaseVertex. Suggested by Jason.

This VS system value will contain the value passed as <basevertex> for
indexed draw calls or the value passed as <first> for non-indexed draw
calls. It can be used to calculate the gl_VertexID as
SYSTEM_VALUE_VERTEX_ID_ZERO_BASE plus SYSTEM_VALUE_FIRST_VERTEX.
From the OpenGL 4.6 spec, 10.4 "Drawing Commands Using Vertex Arrays":
- Page 352:
"The index of any element transferred to the GL by DrawArraysOneInstance
is referred to as its vertex ID, and may be read by a vertex shader as
gl_VertexID. The vertex ID of the ith element transferred is first +
i."
- Page 355:
"The index of any element transferred to the GL by
DrawElementsOneInstance is referred to as its vertex ID, and may be read
by a vertex shader as gl_VertexID. The vertex ID of the ith element
transferred is the sum of basevertex and the value stored in the
currently bound element array buffer at offset indices + i."
Currently the gl_VertexID calculation uses SYSTEM_VALUE_BASE_VERTEX but
this will have to change when the value of gl_BaseVertex is
fixed. Currently its value is broken for non-indexed draw calls because
it must be zero but we are setting it to <first>.
v2: use SYSTEM_VALUE_FIRST_VERTEX as name for the value, instead of
SYSTEM_VALUE_BASE_VERTEX_ID (Kenneth).
v3 (idr): Rebase on Rob Clark converting nir_intrinsics.h to be

This reimplements the test in python with a shell script wrapper that
allows autotools to continue to run the test without realizing that
anything has changed.
Using python has two advantages, first it's portable so this test can be
run on windows as well as Linux since it just requires python, no more
diff, pwd or sh. It's also no longer tied to autotools implementation
details, like the environment variables $srcdir and $abs_builddir,
though the autotools shell wrapper still uses those, which makes it
possible to run the test in meson.

The SPIR-V spec doesn’t specify a size requirement for these and the
equivalent functions in the GLSL spec have explicit alternatives for
doubles. Refract is a little bit more complicated due to the fact that
the final argument is always supposed to be a scalar 32- or 16- bit
float regardless of the other operands. However in practice it seems
there is a bug in glslang that makes it convert the argument to 64-bit
if you actually try to pass it a 32-bit value while the other
arguments are 64-bit. This adds an optional conversion of the final
argument in order to support any type.
These have been tested against the automatically generated tests of
glsl-4.00/execution/built-in-functions using the ARB_gl_spirv branch
which tests it with quite a large range of combinations.
The issue with glslang has been filed here:
https://github.com/KhronosGroup/glslang/issues/1279
v2: Convert the eta operand of Refract from any size in order to make
it eventually cope with 16-bit floats.

The only change neccessary is to change the type of the constant used
to compare against.
This has been tested against the arb_gpu_shader_fp64/execution/

There is an existing macro that is used to choose between either a
float or a double immediate constant based on the bit size of the
first operand to the builtin. This is now changed to use the new
nir_imm_floatN_t helper function to reduce the number of places that
make this decision.

This lets you easily build float immediates just given the bit size.
If we have this single place here to handle this then it will be
easier to add support for 16-bit floats later.

A couple spots were missed for handling of the new INT8/UINT8 base type.
Also de-duplicate get_base_type().. get_scalar_type() had nearly the
same switch statement, with the exception that anything with base_type
that was not scalar would return error_type. So just handle that one
special case in get_scalar_type().

From the SPIR-V spec, OpTypeImage:
"Depth is whether or not this image is a depth image. (Note that
whether or not depth comparisons are actually done is a property of
the sampling opcode, not of this type declaration.)"
The sampling opcodes that specify depth comparisons are
OpImageSample{Proj}Dref{Explicit,Implicit}Lod, so we should set
is_shadow only for these (we were using the deph property of the
image until now).
v2:
- Do the same for OpImageDrefGather.
- Set is_shadow to false if the sampling opcode is not one of these (Jason)
- Reuse an existing switch statement instead of adding a new one (Jason)

Otherwise we may end up trying to coalesce in a case such as
ssa_1 = fadd r1, r2
r3.x = fneg(r2);
r3 = vec4(ssa_1, ssa_1.y, ...)
and that would cause us to move the writes to r3 from the vec to the
fadd which would re-order them with respect to the write from the fneg.
In order to solve this, we just don't coalesce if the destination of the
vec is not SSA. We could try to get clever and still coalesce if there
are no writes to the destination of the vec between the vec and the ALU
source. However, since registers only come from phi webs and indirects,
the chances of having a vec with a register destination that is actually
coalescable into its source is very slim.
