According to isl_gfx7.c:264, the display engine does not support Y
tiled buffers prior to Skylake. But we exposed I915_FORMAT_MOD_Y_TILED
even when querying for a list of modifiers with PIPE_BIND_SCANOUT set,
which we can't support. That led to crashes later when we tried to
create such an image, and isl rightly denied it.
Fixes crashes in wflinfo since c03e79d783, but the bug exists before
that and it's probably worth a stable backport even without that patch.

This duplicates a bit of code from ISL, but the isl_gfx6_filter_tiling
function that we ought to use to filter things relies on surf_info,
which we don't have at this stage. This is probably good enough.

The DIFFUSE thing would write an undefined result if the shader that
failed to compile didn't read VARYING_SLOT_COL0, causing flakes in CI.
This does make 2 piglit tests that were expecting red spuriously pass.

The 3D-pipeline fast clears try to emit FS constants before an FS is
necessarily bound, causing segfaults in dEQP. Plus it flushes the whole
batchbuffer so it'll probably be slower anyway.

We're supposed to map a floating-point value too large to be represented
as fp16 to infinity, however round-to-zero naturally rounds it down to
the largest representable fp16 number instead. The blob emits a bunch of
fixup code to work around this, but instead we can just do what all the
other drivers seem to do and use round-to-nearest-even instead.

Refactor all the linking code with the following objectives:
* Remove linking magic (especially around XFB)
* Cleaner code (obviously)
* Less stage coupling (in case someone ever implements geom/tess)
* Decouple ATTRIBUTE from ATTRIBUTE_BUFFER to enable optimizations
The main hack remaining is doing precision linking here to workaround
linking previously used.

The CAP for packed transform feedback concerns packing of unrelated
variables into the same varying slot. (On Mali, transform feedback is
implemented on a per-slot basis, so different variables need different
slots to be written to different buffers.) However, this requirement is
tangential to the packing of arrays, matrices, and structures inherent
to GLSL. These array-like values need to be packed /within/ their slot,
even though drivers using the CAP (just Panfrost) cannot pack
independent values in the slot. Transform feedback of individual
elements is not independent, after all.

We need to duplicate the subscripted members even if they happen to be
aligned, since the other elements may be passed into the consumer
shader. Fixes on Panfrost:
dEQP-GLES3.functional.transform_feedback.array_element.interleaved.lines.highp_float
Note: the test did pass on main previously due to an elaborate set of
driver hacks. I don't believe the old behaviour was correct regardless.
Only Panfrost is affected by this change and the next, as every other
driver sets PIPE_CAP_PACKED_STREAM_OUTPUT.

Typically, we program the framebuffer dimensions using the destination
surface, however, if we blit a rect from a surface that is smaller than
the destination, the simulator will complain that the TLB load stride
is not large enough to match the destination framebuffer. We can work
around this by programming the smallest size of both surfaces, which
should be okay because the tlb blit path requires that the blit
coordinates are the same for both src and dst.
