When creating frame buffers the alloc callbacks are used in the host
allocations, those same alloc callbacks need to be used when freeing
those allocations but are missing in some places causing the CTS to

It was already computed in brw_shader::assign_curb_setup() so we can use it
in brw_assign_urb_setup().
There was a mismatch between assign_curb_setup() and brw_assign_urb_setup() when
push_sizes were not multiple of REG_SIZE, the first one was aligning every
push_sizes before sum it, while brw_assign_urb_setup() was only aligning the sum
of all push_size.
By luck the only places that did not had a push_size aligned to REG_SIZE only
had one push_size, so this was not an issue.
So here also fixing this mismatch and adding an assert to caught any future
mismatch.

This is mostly about conversions.
Conversions from float to int don't care about signed zero
and in the case of plain f2u/f2i, nan and inf are always
undefined too.
Conversions for int to float can't create nan, so they don't
need preserve_nan.
b2f only cares about preserve_sz, and nothing else.

In some cases, this would incorrectly set higher dpbArraySize
when overwriting already existing dpb slot.
This didn't seem to cause any issues, but the extra slot would
have zero va which was wrong.
Get the actual ref count from codec param, instead of using
cmd->num_refs which always includes current slot. Also add sanity
check that the ref surface was found.

These tests were previously skipped because they contain dynamic loops
in the VS, which can cause GPU resets on VC4. However, (1) the only
tests that cause GPU resets are the ones that have divergent loops and
(2) now, the compiler is able to fail shader linking when it finds
divergent loops.
Therefore, allow tests with non-divergent loops to run on the CI and
add tests with divergent loops to the fail list.

VC4 hardware doesn't have a dispatch mask for the VS, so divergent
loops can have undefined/garbage contents in some execution channels,
potentially causing infinite loops and GPU hangs.
Fail shader linking instead of hanging the GPU when a divergent loop is
detected in a vertex shader.

On V3D 4.2 (Raspberry Pi 4), there is a hardware bug where the binner
can trigger a GPU reset in some situations where primitives are
discarded, such as due to primitive restarts.
The way to avoid this is to force the binner to do always something, by
emitting the proper CL. In this case we decided to always set point
size, as it is a very simple and fast operation.
This fixes resets caused by
dEQP-VK.pipeline.monolithic.input_assembly.primitive_restart.*.

Use information about register usage to decide what to dump for register
summaries. If --allregs, we continue to dump all regs that we have seen
a register write for. Otherwise we dump registers that are written
since last summary (as before) along with regs with the appropriate
usage.
A new column at the start of the line will show a '?' for registers that
don't match the existing usage (ie. they have been written but usage
doesn't match current "draw"). This could simply mean it is the first
"draw" in the render-pass (collecting per-renderpass values). Or it
could mean a mis-attributed or missing register usage. This new column
is only included for a6xx and newer, since older gens don't have usage
specified in xml.
