0c569e22d1 radv: print warnings for famous RADV_PERFTEST options that no longer exist
RADV_PERFTEST=aco no longer exists, ACO is the default compiler.
RADV_PERFTEST=llvm is deprecated, use RADV_DEBUG=llvm instead.

65d23e7fb1 radeon/vcn: Corrected vp9 ref associated data incase of target->codec is NULL
This patch fixes the case where less number of reference surfaces created and destoyed
on need basis. The problem comes when we are refereing old assoiciated data for newly
created target buffer with same address. Here old target buffer destroyed as that
surface is no more used as reference for next frames and when we create a new surface
for the next frame to process we will get the surfaceid and same target address
of destroyed surface.

When new surface/surface->buffer/target ,target->codec is null as we cleared when we
destroy this surface, but per ref_mapping logic, it was taking null associated data
i.e.0 as curr_ref_idx. Hence total reference mapping table goes wrong with wrong data.
Beacuse of this, we have seen corrupted vp9 decoded frames.

9e48e31fa5 tu: Fix DST_INCOHERENT_FLUSH copy/paste error
This was meant to handle incoherent accesses by always flushing them,
but it accidentally checked for the coherent variant instead. As a
result e.g. a vkCmdClearImage() followed by a renderpass using the image
didn't get any flushes, resulting in the same sort of corruption seen
with sysmem renderpass clears. This happened to be exposed via some

b2f475251e pan/mdg: Test for SSA before chasing addresses
It's possible an SSA value depends on a register; in this case, chasing
the source would result in a crash as the chase helper in NIR asserts
is_ssa. Instead we should check a priori that all the argments are in
fact SSA, bailing otherwise.

In the piglit shader exhibiting this bug (by looping over the index),
bailing on the ishl instruction is -necessary-. This is not merely us
being cowardly to avoid seeing through the registers; indeed, if we
wrote away the ishl instruction, the shift itself would have to be
stored in a load/store register (r26/r27) which would preclude reading
it in the loop, creating a register allocation failure later in the
compile. So this is the correct solution due to the restricted
semantics.

63bff6a9f8 gallivm/nir: Lower uniforms to UBOs in llvm draw if the driver didn't request this already
When the llvm draw engine is used for draw shaders in st_program the driver
may not enable the cap PIPE_CAP_PACKED_UNIFORMS, so uniforms are not
be lowered to UBOs. However, llvm doesn't support nir_load_uniform, so lower
the uniforms to UBO now. The multiplier is set to 16 to be the same like in
the TGSI code path.
