713419eef0 panfrost: Rework fixed-function blending 
The fixed-function blend logic uses the following equation: A + B x C.
A, B and C are configurable and can be complemented with negation (for
A and B) or inversion (for C) modifiers. Let's rework the blending
code to take that into account.

Note that we need to update the checksum of a few traces because the
equations we use have changed, leading to small deviations on the
final images. Indeed, there are several valid options for a given GL
blend equation, but the operand selection probably has an impact on the
rounding, leading to those mismatch.

1e7d82c881 nir/algebraic: always lower idiv to shifts if bitops are allowed 
why would you want anything else

The only platform significantly affected by this is Intel where `lower_idiv`
is not set today but neither is `lower_bitops`.  There it seems to still be
a boon over-all.

4b96eb0cc4 etnaviv: Make sure to track different pipe_screens for different DRM device descriptions 
pipe_screens that are created used to be dedublicated directly based on the gpu device file.
If a process created two of them, for example by opening the etnaviv render node twice
and calling `gbm_create_device`, or by opening two card nodes which used kmsro, or any
combination of these things, then for any but the first instance, the gem handles created
for it would be for the first one instead of the intended one, due to them being created
using the same pipe_screen, and buffers allocated for kmsro devices would be allocated using
the wrong file description as well. This can lead to various problems, such as a proccess not
being able to use two cards which use kmsro at the same time, for example.

This patch changes the dedublication to be done based on the gpu device description
rather than based on the gpu device file. This will solve the above mentioned problem,
but there will now be only a few cases in which anything is dedublicated at all.

ccb3d7d8be panfrost: bifrost: disassemble: Fix decoding of next_regs 
next_regs decoding is wrong for the first and last instructions in a
clause:
- the first instruction has its destination encoded in the second reg
  block
- the last instruction has its destination encoded in the first reg block
  (things wrap around)

So, only the last instruction should pass first=true when decoding
next_regs. Fix that by passing the is_last_instruction information
instead of is_first_instruction to the disasm helpers.

bcfec61d1e anv: Add driconf option to disable compression for 16bpp format 
On Fallout4, enabling HIZ_CCS_WT compression for D16_UNORM format
regress the performance by 2%, in order to avoid that disable
compression via driconf option.

The experiment showed that, running Fallout4 with HIZ performs better
than HIZ_CCS and HIZ_CCS_WT. Reason behind that is the benchmark uses
the depth pass with D16_UNORM surfaces format which fills the L3 cache
and next pass doesn't make use of it where we end up clearing cache.

v2:
- Don't add conditional check in isl (Nanley, Jason)
- Move disable_d16unorm_compression flag to instance (Lionel)
- Use plane_format.isl_format (Nanley)

v3:
- Add more descriptive comment (Marcin Ślusarz)
