nir,intel/compiler: Use a fixed subgroup size
The GL_ARB_shader_ballot spec says that gl_SubGroupSizeARB is declared
as a uniform. This means that it cannot change across an invocation
such as a draw call or a compute dispatch. For compute shaders, we're
ok because we only ever use one dispatch size. For fragment, however,
the hardware dynamically chooses between SIMD8 and SIMD16 which violates
the spec. Instead, let's just pick a subgroup size based on the shader
stage. The fixed size we choose for compute shaders is a bit higher
than strictly needed but there's no real harm in that. The advantage is
that, if they do anything interesting with the value, NIR will see it as
an immediate and can optimize better.

nir/lower_subgroups: Lower ballot intrinsics to the specified bit size
Ballot intrinsics return a bitfield of subgroups. In GLSL and some

they return a uvec4. Also, some back-ends would rather pass around

To solve this mess, we make nir_lower_subgroups take a new parameter

intel/compiler/fs: Set up subgroup invocation as a system value
Subgroup invocation is computed using a vector immediate and some
dispatch-aware arithmetic. Unfortunately, due to the vector arithmetic,
and the fact that it's frequently read 16-wide, it's not something that
can easily be CSEd by the back-end compiler. There are a few different
possible approaches to this problem:
1) Emit the code to calculate the subgroup invocation on-the-fly and
trust NIR to do the CSE. This is what we were doing.
2) Add a back-end instruction for the subgroup ID. This has the
advantage of helping the back-end compiler with CSE but has the
downside of very poor scheduling for the calculation because it has
to be emitted in the back-end.
3) Emit the calculation at the top of the program and re-use the
result. This gets rid of the CSE problem but comes at the cost of
an extra live register.
This commit switches us from 1) to 3). We choose to store the subgroup
invocation values as a W type to reduce the impact of the extra live
register. Trusting NIR and using 1) was fine but we're soon going to
want to use the subgroup invocation value for other things in the
back-end compiler and this makes it much easier to do without having to
worry about CSE problems.

Also, DeleteFragmentShadersATI() should not assert on DummyShader, just
remove the hash entry.
Normally one would define a shader after GenFragmentShadersATI(), and
BindFragmentShaderATI() replaces the placeholder with a real object.
However, the specification doesn't say that one has to define a shader
for each allocated ID.

glsl: Allow precision mismatch on dead data with GLSL ES 1.00
Commit
259fc505454ea6a67aeacf6cdebf1398d9947759 added linker error for
mismatching uniform precision, as required by GLES 3.0 specification and
conformance test-suite.
Several Android applications, including Forge of Empires, have shaders
which violate this rule, on a dead varying that will be eliminated.
The problem affects a big number of applications using Cocos2D engine
and other GLES implementations accept this, this poses a serious
application compatibility issue.
Starting from GLSL ES 3.0, declarations with conflicting precision
qualifiers are explicitly prohibited. However GLSL ES 1.00 does not
clearly specify the behavior, except that
"Uniforms are defined to behave as if they are using the same storage in
the vertex and fragment processors and may be implemented this way.
If uniforms are used in both the vertex and fragment shaders, developers
should be warned if the precisions are different. Conversion of
precision should never be implicit."
The word "used" is not clear in this context and might refer to
1) declared (same as GLES 3.x)
2) referred after post-processing, or
3) linked after all optimizations are done.
Looking at existing applications, 2) or 3) seems to be widely adopted.
To avoid compatibility issues, turn the error into a warning if GLSL ES
version is lower than 3.0 and the data is dead in at least one of the
shaders.

quickly get unworkable and every new attribute needs a modification for

To fix that, pass the attribute values in a struct instead. The struct
has a bitmask to specify which members are used. The first three members
(two for the GL version and one for the flags) are always set. If the
bit is not set in the attribute mask then it can be assumed the
attribute has the default value. Drivers will error if unknown bits in
