Before we move a UBO load to a previous location in the block we take a
reference to the instruction after it so we can continue the loop from
there, however, if the load we just moved was already the last instruction
in the block we just want to break the loop right there.

0e3e5146cf ("intel/brw: Use correct instruction for value change check
when coalescing") enabled some new cases that exposed a pre-existing
bug that would turn something like this :
mul.sat(16) %789:F, %787:F, %788:F
mov.g.f0.0(16) %790:F, %789:F
(+f0.0) sel(16) %800:UD, %790:UD, 0u
into this :
mul.sat(16) %790:F, %787:F, %788:F
mov.g.f0.0(16) null:F, null<8,8,1>:F
(+f0.0) sel(16) %800:UD, %790:UD, 0u
The mov[] array can contain the same instruction because it's repeated
for each REG_SIZE writes and a SIMD16 instruction will write 2
REG_SIZE.

in a scenario like:
* begin_rendering(cbuf1:store=DONTCARE, cbuf2)
* draw
* remap(cbuf2, NULL)
* draw
* end_rendering
cbuf1 will be poisoned at the end of the renderpass, but the corresponding
clear call to trigger the poisoning will not be able to detect that this
texture is being written by an async fs, causing a write hazard
unremapping the fb here ensures that all attachments are fb-referenced
as expected in order to guarantee threads sync before memory is poisoned

(cherry picked from commit d8a6ec5985)
When binning with a GS, both VS and GS are active. This means that we
could have to use the safe-const variant for the GS. However we only
emitted VPC state for the binning case with the "normal" GS variant.
Emit the VPC state with the safe-const variant too, and select between
the state variants at link time.
This fixes a few tests like
dEQP-VK.spirv_assembly.instruction.graphics.8bit_storage.32struct_to_8struct.uniform_uint_geom
with TU_DEBUG=gmem,forcebin.

If the render area is restricted to a section of the framebuffer, there
is no need to consider all the framebuffer size when configuring the
supertiles, as only the supertiles coordinates of the affected area will
be submitted.
This allow to create supertiles smaller than the ones in case
considering the full screen, reducing the tiles that need to be
processed.
This also fixes https://gitlab.freedesktop.org/mesa/mesa/-/issues/13218.

So far the driver was configuring the supertiles to be less than 256.
But actually, there can be up to 256, not strictly less than 256.
There is one restriction though: the frame width or height in supertiles
must be less than 256.
It also moves this limit to the limits file, which is shared by v3d and
v3dv.

When we have partial VGRF MOVs with offsets, we will reach
`channels_remaining == 0` with `inst` that is not writing the whole VGRF.
Currently, even though we check `can_coalesce_vars()` for each offset
separately, it will always check if the dst value is not changed only
for the offset from the instruction that satisfied the
`channels_remaining == 0` condition.
Instead, we should remember and use the correct instruction for each
written offset separately.

(cherry picked from commit 0e3e5146cf)
Applications using Mesa built with LLVM 20.1.4 fail to start with
strange segmentfaults/bus errors when radeonsi driver is used. The last
piece of stacktrace looks like
- pipe_reference_described
- pipe_reference
- radeon_bo_reference
- radeon_ws_bo_reference
- radeon_lookup_or_add_real_buffer
Coredump shows the pointer dst passed to pipe_reference_described() is
either unaligned or even invalid, which is the reason of crashing. The
crash goes away when Mesa is built without optimization.
Looking through the related functions, it's found that
radeon_ws_bo_reference() contains unsafe type cast from radeon_bo to
pb_buffer_lean: though the former's first field is just the later, this
violates strict aliasing rules as pb_buffer_lean isn't compatible with
radeon_bo. Such violation ultimately results in miscompilation.
Let's take the address of pb_buffer_lean field, avoiding the unsafe
cast. It's still required to cast pb_buffer_lean back to radeon_bo since
radeon_bo_reference may update the pointer, which is safe as radeon_bo
contains a pb_buffer_lean member and C language permits access members
through a pointer in type of the container.
