This hooks tessellation into various parts of draw, so the
tessellation shaders are used in the correct places as the
last shader of the pipeline.

This is the bulk of the llvm shader builders and tessellation
execution code.
TCS uses a coroutine launcher like compute shaders to handle
barriers. It executes 4-wide with one input vertex per lane.
Tessellation happens before the TES is run.
TES is just a 4-wide launcher, one per primitive is executed,
with one lane per tessellation coordinate input.

This adds the initial draw_tess.h with a define needed
for the interfaces. TCS input array doesn't need to handle
patch inputs so can be smaller.
The TCS context has some dummy values to align the textures/images
properly.

This add support for the tessellation i/o callbacks.
Tessellation requires another level of indirect indexing,
and allows fetches from shader outputs.

This adds the same tessellator code that swr uses, swr should
move to using this copy, unfortunately that wasn't trivial on my first
look.
The p_tessellator wrapper wraps it in a form that is a useful interface
for draw.

This is pretty basic (and a bit crappy at the moment). I think we
might want some sort of overlay in the future and also be able to
trigger captures with F12 or whatever.
To record a capture, set RADV_THREAD_TRACE to something greater than
zero (eg. RADV_THREAD_TRACE=100 will capture frame #100). If the
driver didn't crash (or the GPU didn't hang), the capture file
should be stored in /tmp.
To open that capture, use Radeon GPU Profiler and enjoy your
profiling times with RADV! \o/
Note that thread trace support is quite experimental, only GFX9 is
supported at the moment, and a bunch of useful stuff are still missing
(shader ISA, pipelines info, etc). More is comming soon.

SQTT is a hardware block that collects thread trace data (like
wave occupancy, timings, etc) for every draw/dispatch calls.
It's only supported on GFX9 at the moment but I will add other
generations support soon.
This is the first step towards profiling with RADV!

I want to make sure that I don't introduce warnings in turnip where we
have active work going on, and I also want to make sure that the drivers
we care about testing are warnings-clean.
As with the previous -Werror change, this is for CI only and doesn't
affect end-user builds.

Midgard has the ability to calculate addresses as part of the load/store
pipeline. We'd like to make use of this to avoid doing this work on the
ALU pipes. To do so, when emitting globals/SSBOs/shareds, we walk the
tree looking for address arithmetic to try to parse out something the
hardware can work with, letting the original instructions be DCE'd
ideally. This analysis is done at the NIR level to properly account for
some messy details of vectorization which we'd rather not poke at the
backend level. (Originally I wrote this as a MIR pass but I'm fairly
sure it was wrong.)

When mixing 32/64-bit, we need to align the 32-bit registers to get the
required alignment. This isn't quite enough yet, though, since user
swizzles could bypass and will need to be lowered to 32-bit moves
(outstanding todo).
