Unless all uniforms in the condition can be inlined we can
lower the if/loop. So we rollback added uniforms when one
of uniforms in a if condition fail to be added.

In b9c095cc2c ("panfrost: Rewrite the clear colour packing code"),
packing of clear colours was corrected to use the tilebuffer's
fractional bits, fixing dithering of the clear colour with formats like
RGB565. Unfortunately, that commit did so unconditionally. If the
framebuffer is dithered, but dithering is disabled at the time of
the clear, we would incorrectly dither the clear.
This is a regression, as the old (broken) code passed the relevant CTS
test. What's the catch? Depending on dither state, there are two
formulas to pack tilebuffer colours. We need to handle both. Fixes
KHR-GLES31.core.draw_buffers_indexed.color_masks.

There is a dependence on dithering state about which I was previously
unaware. All these test cases were with dithering enabled, so mark that
down.

Right now opcode_desc struct, used to define data for all the
operations to pack/unpack, include a version field. In theory that
could be used to check if we are retrieving a opcode valid for our hw
version, or to get the correct opcode if a given one changed across hw
versions, or just the same if it didn't change.
In practice that field was not used. So for example, if by mistake we
asked for an opcode defined at version 41, while being on version 33
hardware, we would still get that opcode description.
This commit fixes that, and as we are here we expand the functionality
to allow to define version ranges, just in case a given opcode number
and their description is only valid for a given range.
v2 (from Iago feedback):
* Fixed some comment typos
* Simplified filtering opcode method
* Rename filtering opcode method

Right now there is a helper to get the opcode description from a
packed instruction, used on unpack related instructions. This commit
adds a helper that refactors the equivalent that is already in use on
pack related instructions.
Right now the helper is small, but we plan to extend it on following
commits in order to use the opcode description version field.
To avoid any possible confusion we rename the existing lookup helper.

A lot of CTS tests write a u8vec4 or an i8vec4 to an SSBO. This results
in a lot of shifts and MOVs. When that pattern can be recognized, the
individual 8-bit components can be packed much more efficiently.

Not only does this eliminate a bunch of unnecessary type converting
MOVs, but it can also enable some SWAR. The
dEQP-VK.spirv_assembly.type.vec3.i8.bitwise_xor_frag test does
something about like:
c = a.x ^ b.x;
d = a.y ^ b.y;
e = a.z ^ b.z;
After this change, it looks more like:
uint t = i8vec3AsUint(a) ^ i8vec3AsUint(b);
c = extract_u8(t, 0);
d = extract_u8(t, 1);
e = extract_u8(t, 2);
On Ice Lake, this results in:
SIMD8 shader: 41 instructions. 1 loops. 3804 cycles. 0:0 spills:fills, 5 sends

Emitting the instructions one by one results in two MOV instructions
that won't be propagated. By handling both instructions at once, a
single MOV is emitted. For example, on Ice Lake this helps
dEQP-VK.spirv_assembly.type.vec3.i8.bitwise_xor_frag:
SIMD8 shader: 49 instructions. 1 loops. 4044 cycles. 0:0 spills:fills, 5 sends
SIMD8 shader: 41 instructions. 1 loops. 3804 cycles. 0:0 spills:fills, 5 sends
Without "intel/fs: Allow copy propagation between MOVs of mixed sizes,"
the improvement is still 8 instructions, but there are more instructions
to begin with:
SIMD8 shader: 52 instructions. 1 loops. 4164 cycles. 0:0 spills:fills, 5 sends
SIMD8 shader: 44 instructions. 1 loops. 3944 cycles. 0:0 spills:fills, 5 sends

In the vec4 compiler, 8-bit types should never exist.
In the scalar compiler, 8-bit types should only ever be able to exist on
Gfx ver 8 and 9.
Some instructions are handled in non-obvious ways.

We only end up with one DRI provider per screen, so the only way the

Instead of making LMEM the special case, unify the two paths by setting
up a fake drm_i915_query_memory_regions struct and filling it out based
on OS queries. The important functional change here is that we now pass
system memory through the same GTT size and 3/4 filter that we were
using with the OS queries. This should make behavior consistent on
integrated GPUs regardless of whether or not we have the memory region
query API.
