ir3: Copy propagate immed/const to meta instructions

This is allowed with the new RA, and makes a huge difference in

ir3: Insert output collects in the main shader

We were inserting them in what was NIR's end block with the "end"

Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/9842>

ir3: Add simple CSE pass

RA currently can't handle a live value that's part of a vector and
introduces extra copies. This was espeically a problem for bary.f, where
the bary coords were being split and repeatedly re-collected. But this

ir3/sched: Consider unused destinations when computing live effect

If an instruction's destination is unused, then we shouldn't penalize

aren't read. This works around RA failures when CSE is enabled in some

ir3/sched: Make collects count against tex/sfu limits

In a scenario where there are a lot of texture fetches with constant
coordinates, this prevents the scheduler from scheduling all the setup
instructions after the first group of textures has been scheduled
because they are the only non-syncing thing and scheduling them didn't
decrease tex_delay. Collects with immed/const sources will turn into
moves of those sources, so we should treat them the same.

RA.

ir3/delay: Delete pre-RA repeat handling

It looks likely that any implementation of (rptN) in ir3 will have to
actually create (rptN) instructions after RA, which means that this can
be dropped.

Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/9842>

ir3: Rewrite delay calculation

The old delay calculation relied on the SSA information staying around,
and wouldn't work once we start introducing phi nodes and making
"normal" values defined in multiple blocks not array regs anymore.
What's worse is that properly inserting phi nodes when splitting live
ranges would make that code even more complicated, and this was the last
place post-RA that actually needed that information.

The new version only compares the physical registers of sources and
destinations. It works by going backwards up to a maximum number of
cycles, so it might be slightly slower when the definition is closer but
should be faster when it is farther away.

To avoid complicating the new method, the old method is kept around, but
only for pre-RA scheduling and it can therefore be drastically
simplified as the array case can be dropped.

ir3_delay_calc() is split into a few variants to avoid an explosion of
boolean arguments in users, especially now that merged_regs now has to
be passed to it.

The new method is a little more complicated when it comes to handling
(rptN), because both the assigner and consumer may be (rptN). This adds
some unit tests for those cases, in addition to dropping the to-SSA code
in the test harness since it's no longer needed.

Finally, ir3_legalize has to be switched to using physical registers for
the branch condition. This was the one place where IR3_REG_SSA remained
after RA.

Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/9842>

ir3: Make branch conditions non-SSA

In particular, make sure they have a physreg assigned. This was the last
place after RA where SSA registers were created, which won't work with
the new post-RA delay calculation that relies on the physreg.

ir3/delay: Fix full->half and half->full delay

The current compiler never does this, but the new compiler will start to

Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/9842>

ir3: Add ir3_register::array.base

There were two different approaches I saw in the post-RA code for
figuring out what regiser range a relative access touched:

1. Use reg->array.offset and reg->array.size. This is wrong in case
   reg->array.offset was non-zero before RA, because array.size is
   the size of the whole array and array.offset has the const offset
   within the array baked in.
2. Lookup the array from the array ID and use the base + range there.
   This is correct, but won't work with the new RA, where an array might
   not always be assigned to the same register.

This replaces both methods with a new ir3_register::array.base field,
and switches all the users I could find to it.

Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/9842>

ir3: Prepare for instructions with multiple destinations

To simplify the pre-RA merge set code and express the result live-range
splitting in RA, we need to add support for parallel copy instructions,
and for the merge set code these parallel copies need to be in SSA form.
Parallel copies have multiple destinations by necessity, but there was
no way to express this in the existing IR. In particular there was no
support for marking a register as being a destination, and no support
for indicating which destination register out of several an SSA source
refers to. This replaces ir3_register::instr with ir3_register::def and
re-purposes ir3_register::instr. I haven't propagated this into common
helpers, like ssa(), because that would vastly increase the amount of
churn and the number of places that produce such instructions should be
limited -- only RA will create parallel copies and they will be
destroyed right after RA. In the future swz will have multiple
destinations too, but it will only be created after RA via parallel copy
lowering.

panfrost: Reduce pan_image_state indirection

panfrost: Don't CRC mipmapped textures

CRC is intended for final render targets and especially for UI, not the
kind of things you'd mipmap. Meanwhile CRC only works for a single
level, meaning at any given point, half the CRC buffer would be wasted
for a full miptree.

"Arm Mali Best Practices Guide" tells developers that the DDK only
enables CRC for non-mipmapped resources (at least the Vulkan DDK), so
let's do the same, save some memory, and simplify our code.
