This seems slightly more correct because it means that the flushes
happen before any clears or resolves implied by the subpass transition.

Previously, we just used all the channels regardless of the format.
This is less than ideal because some channels may have undefined values
and this should be ok from the client's perspective. Even though the
driver should do the correct thing regardless of what is in the
undefined value, it makes things less deterministic. In particular, the
driver may choose to fast-clear or not based on undefined values. This
level of nondeterminism is bad.

This fixes a pile of hangs caused by the recent shuffling of resolves
and transitions. The particularly problematic case is when you have at
least three attachments with load ops of CLEAR, LOAD, CLEAR. In this
case, we execute the first CLEAR followed by a MI memcpy to copy the
clear values over for the LOAD followed by a second CLEAR. The MI
commands cause the first CLEAR to hang which causes us to get stuck on
the 3DSTATE_MULTISAMPLE in the second CLEAR.
We also add guards for BLORP to fix the same issue. These shouldn't
actually do anything right now because the only use of indirect clears
in BLORP today is for resolves which are already guarded by a render
cache flush and CS stall. However, this will guard us against potential
issues in the future.

This commit completely reworks aux tracking. This includes a number of
somewhat distinct changes:
1) Since we are no longer fast-clearing multiple slices, we only need
to track one fast clear color and one fast clear type.
2) We store two bits for fast clear instead of one to let us
distinguish between zero and non-zero fast clear colors. This is
needed so that we can do full resolves when transitioning to
PRESENT_SRC_KHR with gen9 CCS images where we allow zero clear
values in all sorts of places we wouldn't normally.
3) We now track compression state as a boolean separate from fast clear
type and this is tracked on a per-slice granularity.
The previous scheme had some issues when it came to individual slices of
a multi-LOD images. In particular, we only tracked "needs resolve"
per-LOD but you could do a vkCmdPipelineBarrier that would only resolve
a portion of the image and would set "needs resolve" to false anyway.
Also, any transition from an undefined layout would reset the clear
color for the entire LOD regardless of whether or not there was some
clear color on some other slice.
As far as full/partial resolves go, he assumptions of the previous
scheme held because the one case where we do need a full resolve when
CCS_E is enabled is for window-system images. Since we only ever
allowed X-tiled window-system images, CCS was entirely disabled on gen9+
and we never got CCS_E. With the advent of Y-tiled window-system
buffers, we now need to properly support doing a full resolve of images
marked CCS_E.
v2 (Jason Ekstrand):
- Fix an bug in the compressed flag offset calculation
- Treat 3D images as multi-slice for the purposes of resolve tracking
v3 (Jason Ekstrand):

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.

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.

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

in the query pool (starting at query) where N is the number of bits
set in the view mask in the subpass the query is used in.
How the numerical results of the query are distributed among the
queries is implementation-dependent. For example, some implementations
may write each view's results to a distinct query, while other
implementations may write the total result to the first query and write
zero to the other queries. However, the sum of the results in all the
queries must accurately reflect the total result of the query summed
over all views. Applications can sum the results from all the queries to
compute the total result."
In our case we only really emit a single query (in the first query index)
that stores the aggregated result for all views, but we still need to manage
availability for all the other query indices involved, even if we don't
actually use them.
This is relevant when clients call vkGetQueryPoolResults and pass all N
