nir: Combine if_uses with instruction uses

Every nir_ssa_def is part of a chain of uses, implemented with doubly linked
lists.  That means each requires 2 * 64-bit = 16 bytes per def, which is
memory intensive. Together they require 32 bytes per def. Not cool.

To cut that memory use in half, we can combine the two linked lists into a
single use list that contains both regular instruction uses and if-uses. To do
this, we augment the nir_src with a boolean "is_if", and reimplement the
abstract if-uses operations on top of that list. That boolean should fit into
the padding already in nir_src so should not actually affect memory use, and in
the future we sneak it into the bottom bit of a pointer.

However, this creates a new inefficiency: now iterating over regular uses
separate from if-uses is (nominally) more expensive. It turns out virtually
every caller of nir_foreach_if_use(_safe) also calls nir_foreach_use(_safe)
immediately before, so we rewrite most of the callers to instead call a new
single `nir_foreach_use_including_if(_safe)` which predicates the logic based on
`src->is_if`. This should mitigate the performance difference.

There's a bit of churn, but this is largely a mechanical set of changes.

radv: copy stages instead of serializing NIR for GPL with the RETAIN flag

retain shaders because we can't know if the LTO pipeline will be a
cache hit as well.

Though, serializing the NIR is too costly and most of the libraries
took more than 10ms to be created, which isn't acceptable. To fix this,
keep track of the shaders stage info for libs with the RETAIN flag.

This also allows us to be lazy about mapping things to the KMS side, so
only clients that really want a KMS handle actually do that, which stops
us from ending up with a bunch of junk mapped to DCP (e.g. X11 clients
always request SCANOUT even under XWayland).

asahi: Implement valid buffer range tracking

A common pattern is to allocate a vertex/etc buffer and write to it in
subsets. Some games interleave this with draw calls using the buffer.
This causes very expensive flushing for every draw call.

Fix this by tracking which range of a buffer has been written to, and
elide syncs when the range was previously uninitialized.

Fixes Source engine game performance and probably helps a bunch of

agx: Coalesce more collects

Try harder to coalesce collects, by trying to allocate collects only to regions
of the register file where we actually have a full vector worth of registers
free. If we already know that the vector will be blocked later, it's not a good
base register to pick since we'd be force to shuffle later. So, this tweak to
the collect coalescing heuristic lets us eliminate a pile of pointless copying.

shader-db results are excellent. Note that, although we use more registers,
none of the shaders tested had their thread count affected, likely because the
max HURT isn't too high and most of the scary % here is from using a few more
registers when the register pressure is already low. In the near future, that
property will become guaranteed thanks to live range splitting, too.

Add information about the relationship between program register usage and
program occupancy (the maximum number of threads that may execute concurrently
on a single shader core). This table is derived from studying the
maxTotalThreadsPerThreadgroup property in Metal while varying the register
usage, something I blogged about a few years back. It's probably not 100%
accurate and it hasn't been tested against hardware, but it matters "only" for

In the (near) future, RA will be able to make use of this information to know
exactly when it can use more registers without hurting performance. In the
present, it's just used for better shader-db statistics.
