lima/ppir: split ppir_op_undef into undef and dummy again

Those were renamed/merged some time ago but it turns out that
ppir_op_undef can't be shared.
It was being used for undefined ssa operations and for read-before-write
operations that may happen to e.g. uninitialized registers (non-ssa)
inside a loop.
We really don't want to reserve a register for the undef ssa case, but
we must reserve and allocate register for the unitialized register case
because when it happens inside a loop it may need to hold its value
across iterations.

This dummy node might be eliminated with a code refactor in ppir in case
we are able to emit the write and allocate the ppir_reg before we emit
the read. But a major refactor we need this to keep this code to avoid
apparent regressions with the new liveness analysis implementation.

anv: Rework CCS memory handling on TGL-LP

The previous way we were attempting to handle AUX tables on TGL-LP was
very GL-like.  We used the same aux table management code that's shared
with iris and we updated the table on image create/destroy.  The problem
with this is that Vulkan allows multiple VkImage objects to be bound to
the same memory location simultaneously and the app can ping-pong back
and forth between them in the same command buffer.  Because the AUX
table contains format-specific data, we cannot support this ping-pong
behavior with only CPU updates of the AUX table.

The new mechanism switches things around a bit and instead makes the aux
data part of the BO.  At BO creation time, a bit of space is appended to
the end of the BO for AUX data and the AUX table is updated in bulk for
the entire BO.  The problem here, of course, is that we can't insert the
format-specific data into the AUX table at BO create time.

Fortunately, Vulkan has a requirement that every TILING_OPTIMAL image
must be initialized prior to use by transitioning the image from
VK_IMAGE_LAYOUT_UNDEFINED to something else.  When doing the above
described ping-pong behavior, the app has to do such an initialization
transition every time it corrupts the underlying memory of the VkImage
by using it as something else.  We can hook into this initialization and
use it to update the AUX-TT entries from the command streamer.  This way
the AUX table gets its format information, apps get aliasing support,
and everyone is happy.

One side-effect of this is that we disallow CCS on shared buffers.
We'll need to fix this for modifiers on the scanout path but that's a
task for another patch.  We should be able to do it with dedicated
allocations.

    for the flush at the end of cmd_buffer_begin_subpass.

 2. Because BLORP ops such as vkCmdClearAttachments may come in the

    flush after the blorp op.

radv: Allow DCC & TC-compat HTILE with VK_IMAGE_CREATE_EXTENDED_USAGE_BIT.

I misunderstood the flag when initially disabling. But this flag
only does something with mutable formats. If we have DCC and
mutable formats, the formats are close enough that the allowed
usage flags are not meaningfully different nor used during
allocation.

ac/llvm: fix missing casts in ac_build_readlane()

Because ac_build_optimization_barrier() overwrites the original
src_type, we have to keep track of it before emitting that barrier.
Otherwise, wrong conversions are expected for pointers or small
bitsizes.

By doing this, we no longer need to do the cast dance in
ac_build_readlane_no_opt_barrier(), it was just necessary for
ac_build_optimization_barrier().

This fixes a bunch of crashes with subgroups related tests when
RADV_DEBUG=checkir is enabled, and it also fixes a compiler crash
with The Surge 2.

drisw: Cache the depth of the X drawable

This is not always ->rgbBits, because there are cases where that could
be 32 but we're (legally) bound to a depth-24 pixmap. The important
thing to have match here is the actual server-side notion of depth.  You
can look this up (at modest expense) from the xlib visual info if the
fbconfig has a visual. But it might not, so if not, fetch it (at
slightly greater expense) from XGetGeometry. Do this at GLX drawable
creation so you don't have to do it on the SwapBuffers path.

Apparently this fixes glx/glx-swap-singlebuffer, which is unintentional
but quite pleasant.
