We can start reading the URB at the first offset that contains varyings
that are actually read in the URB. We still need to make sure that we
read at least one varying to honor hardware requirements.
This helps alleviate a problem introduced with 99df02ca26f61 for
separate shader objects: without separate shader objects we assign
locations sequentially, however, since that commit we have changed the
method for SSO so that the VUE slot assigned depends on the number of
builtin slots plus the location assigned to the varying. This fixed
layout is intended to help SSO programs by avoiding on-the-fly recompiles
when swapping out shaders, however, it also means that if a varying uses
a large location number close to the maximum allowed by the SF/FS units
(31), then the offset introduced by the number of builtin slots can push
the location outside the range and trigger an assertion.
This problem is affecting at least the following CTS tests for
enhanced layouts:
KHR-GL45.enhanced_layouts.varying_array_components
KHR-GL45.enhanced_layouts.varying_array_locations
KHR-GL45.enhanced_layouts.varying_components
KHR-GL45.enhanced_layouts.varying_locations
which use SSO and the the location layout qualifier to select such
location numbers explicitly.
This change helps these tests because for SSO we always have to include
things such as VARYING_SLOT_CLIP_DIST{0,1} even if the fragment shader is
very unlikely to read them, so by doing this we free builtin slots from
the fixed VUE layout and we avoid the tests to crash in this scenario.
Of course, this is not a proper fix, we'd still run into problems if someone
tries to use an explicit max location and read gl_ViewportIndex, gl_LayerID or
gl_CullDistancein in the FS, but that would be a much less common bug and we
can probably wait to see if anyone actually runs into that situation in a real
world scenario before making the decision that more aggresive changes are
required to support this without reverting 99df02ca26f61.
v2:
- Add a debug message when we skip clip distances (Ilia)
- we also need to account for this when we compute the urb setup
for the fragment shader stage, so add a compiler util to compute
the first slot that we need to read from the URB instead of
replicating the logic in both places.
v3:
- Make the util more generic so it can account for all unused slots
at the beginning of the URB, that will make it more useful (Ken).
- Drop the debug message, it was not what Ilia was asking for.

Allows the instructions to be compacted. The documentation claims that
some of these only accept UD types, even though the type doesn't change
the operation performed. Just normalize the types to ensure we get
instruction compaction.
The only functional changes are for FBL and CBIT (always use UD types)
and FBH (always use the same types).

The status quo is quite the mess:
1. tgsi_exec will do a per-channel computation, and store the dst[0]
result (significand) correctly for each channel. The dst[1] result
(exponent) will be written to the first bit set in the writemask.
So per-component calculation only works partially.
2. r600 will only do a single computation. It will replicate the
exponent but not the significand.
3. The docs pretend that there's per-component calculation, but even
get dst[0] and dst[1] confused.
4. Luckily, st_glsl_to_tgsi only ever emits single-component instructions,
and kind-of assumes that everything is replicated, generating this for
the dvec4 case:
DFRACEXP TEMP[0].xy, TEMP[1].x, CONST[0][0].xyxy
DFRACEXP TEMP[0].zw, TEMP[1].y, CONST[0][0].zwzw
DFRACEXP TEMP[2].xy, TEMP[1].z, CONST[0][1].xyxy
DFRACEXP TEMP[2].zw, TEMP[1].w, CONST[0][1].zwzw
Settle on the simplest behavior, which is single-component calculation
with replication, document it, and adjust tgsi_exec and r600.

Sourcing the exponent for the zw destination pair from Z is consistent
with both tgsi_exec and gallivm. In practice, st_glsl_to_tgsi always
generates per-channel instructions anyway.

A tempting alternative fix would be adding a lock/unlock pair in
util_queue_fence_is_signalled. However, that wouldn't actually
improve anything in the semantics of util_queue_fence_is_signalled,
while making that test much more heavy-weight. So this lock/unlock
pair in util_queue_fence_destroy for "flushing out" other threads
that may still be in util_queue_fence_signal looks like the better
fix.

The hardware usually does this automatically. However, we upgrade
depth to Z32_FLOAT to enable TC-compatible HTILE, which means the
hardware no longer clamps the comparison value for us.
The only way to tell in the shader whether a clamp is required
seems to be to communicate an additional bit in the descriptor
table. While VI has some unused bits in the resource descriptor,
those bits have unfortunately all been used in gfx9. So we use
an unused bit in the sampler state instead.

Overriding the default (no-op) swizzle is clearly counter-productive,
since the whole point is putting the destination register as one of
the source operands so that it remains unmodified when the assignment
condition is false.
Fragment depth and stencil outputs are a special case due to how their
source swizzles are manipulated in translate_src when compiling to
TGSI.

The loop here tries to be safe, but in doing so, it ends up doing

variable (inst) could be deleted and nothing else. However, this

Triggering the push model when 64-bit inputs are involved is not easy due to
the constrains on the maximum number of registers that we allow for this mode,
however, for GS with 'points' primitive type and just a couple of double
varyings we can trigger this and it just doesn't work because the
implementation is not 64-bit aware at all. For now, let's make sure that we
don't attempt this model whith 64-bit inputs and we always fall back to pull
model for them.
Also, don't enable the VUE handles in the thread payload on the fly when we
find an input for which we need the pull model, this is not safe: if we need
to resort to the pull model we need to account for that when we setup the
thread payload so we compute the first non-payload register properly. If we
didn't do that correctly and we enable it on-the-fly here then we will end up
VUE handles on the first non-payload register which will probably lead to
GPU hangs. Instead, always enable the VUE handles for the pull model so we
can safely use them when needed. The GS is going to resort to pull model
almost in every situation anyway, so this shouldn't make a significant
difference and it makes things easier and safer.
v2: Always enable the VUE handles for pull model, this is easier and safer
and the GS is going to fallback to pull model almost always anyway (Ken)
v3: Only clamp the URB read length if we are over the maximum reserved for
push inputs as we were doing in the original code (Ken).
v4: No need to clamp the urb read length if invocations > 1
