The primary difference between the KHR and EXT versions of the extension
is that the KHR provides the address at AllocateMemory time for replay
so we can replay it safely without moving to a sparse address model.

Without looking at the assembly or something, I'm not sure what the
compiler does here. The brw_reg_type enum is marked packed, so I'm
guess that it gets represented as a uint8_t. That's the only reason I
could think that comparing with -1 would be always true.
This patch adds the same cast that exists in brw_hw_type_to_reg_type.
It might be better to add a #define outside the enum for
BRW_REGISTER_TYPE_INVALID as (enum brw_reg_type)-1.

Use this new instruction introduced in Gen12. The instruction itself is
smaller, and it also allows us to emit a single instruction to all
stages that have the same push constant buffers (e.g. when they don't
have constant buffers).
There's one restriction to use this instruction, though: the length
field is only 5 bits long, so we need to check whether we can use it,
and fallback to the old 3DSTATE_CONSTANT_XS if that field is >= 32.

Store push_ranges in ascending order, and only "shift" them to the end
of the array during state packet emission.
We don't need this workaround with the new 3DSTATE_CONSTANT_ALL packet.
So instead of applying the workaround here just for GEN < 12 (which
requires and extra loop through all the ranges to figure out if we
should shift them or not), we simply move the whole logic to the state
emission code. At that point, in a later commit, we are already looping
through all of the ranges anyway to check which packet we will be using,
so we might as well implement the workaround there, where it is going to
be used.

Previously we only had a somewhat difficult to parse state machine
tracking the context ID.
What we really only need to do to decide if the delta between 2
reports (r0 & r1) should be accumulated in the query result is :
* whether the r0 is tagged with the context ID relevant to us
* if r0 is not tagged with our context ID and r1 is: does r0 have a
invalid context id? If not then we're in a case where i915 has
resubmitted the same context for execution through the execlist

If we read the OA reports late enough after the query happens, we can
get a timestamp in the report that is significantly in the past
compared to the start timestamp of the query. The current code must
deal with the wraparound of the timestamp value (every ~6 minute). So
consider that if the difference is greater than half that wraparound
period, we're probably dealing with an old report and make the caller
aware it should read more reports when they're available.

This reverts commit 52c7df1643. The pass,
while clearly useful for some shaders, has at least three bugs that I
was able to find fairly quickly:
1. It doesn't work for type-converting MOVs because f > 0 is not the
same as f2i(f) > 0
2. CSEL is a 3src instruction and only supports one source type; it
doesn't take this into account and tries to create instructions
which do a F compare and a D select. This is especially nasty to
debug because you don't see that in the dumped assembly because we
don't properly assert that types are the same in codegen.
3. While you can handle 2, in theory, by reinterpreting types, you
can't do that in the presence of source modifiers. This pass
doesn't even attempt to detect that.
Those are just the ones I found with the one almost trival shader I was
debugging. There very likely may be more and. Best thing to do for now
is just shut it off until someone has the time to figure out how to do
this properly and write tests to ensure it's correct.

Instead of blindly dirtying descriptors and push constants the moment we
see a pipeline change, check to see if it actually changes the bind

one CPU-limited example running with the Dawn WebGPU implementation when
running on my laptop.
NOTE: This effectively reverts beca63c6c0. While it was a nice
optimization, it was based on prog_data and we can't do that anymore
once we start allowing the same binding table to be used with multiple
different pipelines.

Instead of dirtying all graphics or all compute based on binding point,
we're now much more careful. We first check to see if the actual
descriptor set changed and then only dirty the stages used by that
descriptor set. For dynamic offsets, we keep a bitfield per-stage of
which offsets are actually used in that stage and we only dirty push
constants and descriptors if that stage has dynamic offsets AND those
offsets actually change.

It theoretically could be more efficient but the real point here is that

This substantially reworks both the state setup side of push constant
handling and the pipeline compile side. The fundamental change here is
that we're no longer respecting the prog_data::param array and instead
are just instructing the back-end compiler to leave the array alone.
This makes the state setup side substantially simpler because we can now
just memcpy the whole block of push constants and don't have to
upload one DWORD at a time.
This also means that we can compute the full push constant layout
up-front and just trust the back-end compiler to not mess with it.
Maybe one day we'll decide that the back-end compiler can do useful
things there again but for now, this is functionally no different from
what we had before this commit and makes the NIR handling cleaner.
