Even though the blorp pass looks a bit on the sketchy side, the end
result in the Vulkan driver is very nice. Instead of having this weird
case where you do a fast clear and then maybe have to resolve, we just
do the ambiguate and are done with it. The ambiguate does exactly what
we want of setting all the CCS values to 0 which puts it into the
pass-through state.
This should also improve performance a bit in certain cases. For
instance, if we did a transition from UNDEFINED to GENERAL for a surface
that doesn't have CCS enabled all the time, we would end up doing a
fast-clear and then a full resolve which ends up touching every byte in
the main surface as well as the CCS. With the ambiguate pass, that
transition only touches the CCS.

Now that this isn't a multi-case if and it's just the one case, it's a

This pass performs an "ambiguate" operation on a CCS-compressed surface
by manually writing zeros into the CCS. On gen8+, ISL gives us a fairly
detailed notion of how the CCS is laid out so this is fairly simple to
do. On gen7, the CCS tiling is quite crazy but that isn't an issue
because we can only do CCS on single-slice images so we can just blast
over the entire CCS buffer if we want to.

The current strategy we use for managing resolves has an issues where we
track clear colors and the need for resolves per-LOD but we still allow
resolves of only a subset of the slices in any given LOD and doing so
sets the "needs resolve" flag for that LOD to false while leaving the
remaining layers unresolved. This patch is only the first step and does
not, by itself fix anything. However, it's fairly self-contained and
splitting it out means any performance regressions should bisect to this
nice obvious commit rather than to the giant "rework aux tracking"
commit.
Nanley and I did some testing and none of the applications we tested
even tried to fast-clear anything other than the first slice of an
image. The test was done by adding a printf right before we call
blorp_fast_clear if we were every going to touch any slice other than
the first with a fast-clear. Due to the way the original code was
structured, this would not have included applications which only cleared
a subset of layers. The applications tested were:
* All Sascha Willems demos
* Aztec Ruins
* Dota 2
* The Talos Principle
* Mad Max
* Warhammer 40,000: Dawn of War III
* Serious Sam Fusion 2017: BFE
While not the full list of shipping applications, it's a pretty good
spread and covers most of the engines we've seen running on our driver.
If this is ever shown to be a performance problem in the future, we can
reconsider our strategy.

This moves it to being based on layout_to_aux_usage instead of being
hard-coded based on bits of a priori knowledge of how transitions
interact with layouts. This conceptually simplifies things because
we're now using layout_to_aux_usage and layout_supports_fast_clear to
make resolve decisions so changes to those functions will do what one
expects.
There is a potential bug with window system integration on gen9+ where
we wouldn't do a resolve when transitioning to the PRESENT_SRC layout
because we just assume that everything that handles CCS_E can handle it
all the time. When handing a CCS_E image off to the window system, we
may need to do a full resolve if the window system does not support the
CCS_E modifier. The only reason why this hasn't been a problem yet is
because we don't support modifiers in Vulkan WSI and so we always get X
tiling which implies no CCS on gen9+. This patch doesn't actually fix
that bug yet but it takes us the first step in that direction by making
us actually pick the correct resolve op. In order to handle all of the
cases, we need more detailed aux tracking.

Otherwise loop unrolling will fail to see the actual cost of
the unrolling operations when the loop body contains 64-bit integer
instructions, and very specially when the divmod64 lowering applies,
since its lowering is quite expensive.
Without this change, some in-development CTS tests for int64
get stuck forever trying to register allocate a shader with
over 50K SSA values. The large number of SSA values is the result
of NIR first unrolling multiple seemingly simple loops that involve
int64 instructions, only to then lower these instructions to produce
a massive pile of code (due to the divmod64 lowering in the unrolled
instructions).
With this change, loop unrolling will see the loops with the int64
code already lowered and will realize that it is too expensive to
unroll.
v2: Run nir_algebraic first so we can hopefully get rid of some of
the int64 instructions before we even attempt to lower them.

We need to access the pipeline layout to compute correct dynamic

The Vulkan spec states that VkPipelineLayout objects must not be
destroyed while any command buffer that uses them is in the recording
state, but it permits them to be destroyed otherwise. This means that
applications are allowed to free pipeline layouts after command recording
is finished even if there are pipeline objects that still exist and were
created with these layouts.
There are two solutions to this, one is to use reference counting on
pipeline layout objects. The other is to avoid holding references to
pipeline layouts where they are not really needed.
This patch takes a step towards the second option by making the
pipeline shader compile code take pipeline layout from the
VkGraphicsPipelineCreateInfo provided rather than the pipeline
object.
A follow-up patch will remove any remaining uses of the layout field
so we can remove it from the pipeline object and avoid the need
for reference counting.
