So far ANV was advertising 4 bits for both subTexelPrecisionBits and
mipmapPrecisionBits. But these values were not actually verified.
But it seems the right value is actually 8 bits for both cases.
Unfortunately Intel PRM does not clarify how many bits the hardware use.
For the mipmap case, there is the following reference in PRM Volume 6
(3D Media GPGPU), specifically in LOD Computation Pseudocode:
```
Bias: S4.8
MinLod: U4.8
MaxLod: U4.8
Base: U4.1
MIPCnt: U4
SurfMinLod: U4.8
ResMinLod: U4.8
``
We have other clues, though:
- On one side, dEQP-VK.texture.explicit_lod.* tests fail when using 4
bits, but work when using 8 bits. These tests try to mimic the expected
behaviour as much real as possible, and they use the reported
subTexelPrecisionBits and mipmapPrecisionBits reported to get this.
- On the other side, the equivalent driver for Windows is reporting 8
bits for both elements. Not sure if they got to verify it from the PRM
or from a diffent source.

From the OpenGL 4.60.5 spec, section 4.4.1 Input Layout Qualifiers,
Page 67, (Location aliasing):
" Further, when location aliasing, the aliases sharing the location
must have the same underlying numerical type and bit
width (floating-point or integer, 32-bit versus 64-bit, etc.) and
the same auxiliary storage and interpolation qualification."
Additionally, we have improved the linker error descriptions.
Specifically, when taking structs into account we were producing a
linker error because we assumed that all components in each location
were used and that would cause component aliasing. This is not
accurate of the actual problem. Now, the failure specifies that the
underlying numerical type incompatibility is the cause for the
failure.
Fixes the following piglit test:
tests/spec/arb_enhanced_layouts/linker/component-layout/vs-to-fs-width-mismatch-double-float.shader_test
v2:
- Do not assert if we see invalid numerical types. These come
straight from shader code, so we should produce linker errors if
shaders attempt to do location aliasing on variables that are not
numerical such as records.
- While we are at it, improve error reporting for the case of
numerical type mismatch to include the shader stage.
v3:
- Allow location aliasing of images and samplers. If we get these
it means bindless support is active and they should be handled
as 64-bit integers (Ilia)
- Make sure we produce link errors for any non-numerical type
for which we attempt location aliasing, not just structs.
v4:
- Rebased with minor fixes (Andres).
- Added fixing tag to the commit log (Andres).
v5:
- Remove the helper function and check individually for the
underlying numerical type and bit width (Timothy).
- Implicitly, assume that any non-treated type which is checked for
its underlying numerical type is either integer or
float and has a defined bit width (Timothy).
- Implicitly, assume that structs are the only non-treated
non-numerical type (Timothy).
- Improve the linker error descriptions and commit log (Andres).

When using quads, instead of mapping the elements to the next 4 local
invocation indices, we map the two next in the "current" row and two
next in the "next row". A side effect is that a thread will execute
the indices in a different order.
We now perform the lowering of both local invocation ID and index
together -- and don't rely anymore on lowering done by
nir_lower_system_values. That is convenient when doing the math for
quads, because we need X and Y to get the right invocation index.
When the pass progresses, fold the constants and clean up to reduce
the noise from the indexing math.
This implements the derivative_group_quadsNV semantics from
NV_compute_shader_derivatives.

When I implemented opt_if_loop_last_continue() I had restricted
this pass from moving other if-statements inside the branch opposite
the continue. At the time it was causing a bunch of spilling in
shader-db for i965.
However Samuel Pitoiset noticed that making this pass more aggressive
significantly improved the performance of Doom on RADV. Below are
the statistics he gathered.
28717 shaders in 14931 tests
Totals:
SGPRS: 1267317 -> 1267549 (0.02 %)
VGPRS: 896876 -> 895920 (-0.11 %)
Spilled SGPRs: 24701 -> 26367 (6.74 %)
Code Size: 48379452 -> 48507880 (0.27 %) bytes
Max Waves: 241159 -> 241190 (0.01 %)
Totals from affected shaders:
SGPRS: 23584 -> 23816 (0.98 %)
VGPRS: 25908 -> 24952 (-3.69 %)

Code Size: 2471392 -> 2599820 (5.20 %) bytes

The codesize increases is related to Wolfenstein II it seems largely
due to an increase in phis rather than the existing jumps.

Consider the following search expression and NIR sequence:
('iadd', ('imul', a, b), b)
ssa_2 = imul ssa_0, ssa_1
ssa_3 = iadd ssa_2, ssa_0
The current algorithm is greedy and, the moment the imul finds a match,
it commits those variable names and returns success. In the above
example, it maps a -> ssa_0 and b -> ssa_1. When we then try to match
the iadd, it sees that ssa_0 is not b and fails to match. The iadd
match will attempt to flip itself and try again (which won't work) but
it cannot ask the imul to try a flipped match.
This commit instead counts the number of commutative ops in each
expression and assigns an index to each. It then does a loop and loops
over the full combinatorial matrix of commutative operations. In order
to keep things sane, we limit it to at most 4 commutative operations (16
combinations). There is only one optimization in opt_algebraic that
goes over this limit and it's the bitfieldReverse detection for some UE4
demo.
