Allow UBO relocs and only emitting uniforms that are actually used.
GC7000Lite has no address register, so upload uniforms to a UBO object to
LOAD from.
I removed the code to check for changes to individual uniforms and just
reupload to entire uniform state when the state is dirty. I think there
was very limited benefit to it and it isn't compatible with relocs.

This just eliminates tautological / contradictory compares that are used
for bcsel and other non-if-statement cases. If-statements are not
affected because removing flow control can cause the i965 instrution
scheduler to create some very long live ranges resulting in unncessary
spilling. This causes some shaders to fall of a performance cliff.
Since many small if-statements are already flattened to bcsel, this
optimization covers more than 68% of the possible cases (2417 shaders
helped for instructions on Skylake vs. 3554).

A while ago, we started deferring GEM object closure and VMA release
until buffers were idle. This had some unforeseen interactions with
external buffers.
We keep imported buffers in hash tables, so if we have repeated imports
of the same GEM object, we map those to the same iris_bo structure.
This is critical for several reasons. Unfortunately, we broke this
assumption. When freeing a non-idle external buffer, we would drop it
from the hash tables, then move it to the zombie list. If someone
reimported the same GEM object, we would not find it in the hash tables,
and go ahead and make a second iris_bo for that GEM object. But the old
iris_bo would still be in the zombie list, and so we would eventually
call GEM_CLOSE on it - closing a BO that should have still been live.
To work around this, we defer removing a BO from the hash tables until
it's actually fully closed. This has the strange effect that an
external BO may be on the zombie list, and yet be resurrected before
it can be properly cleaned up. In this case, we remove it from the
list so it won't be freed.
Fixes severe instability in Weston, which was hitting EINVALs and
ENOENTs from execbuf2, due to batches referring to a GEM object that
had been closed, or at least had its VMA torched.
Fixes: 457a55716e ("iris: Defer closing and freeing VMA until buffers are idle.")
Everybody importing an external buffer was looking it up in the hash
table, then referencing it. We can just do that in the helper instead,
which also gives us a convenient spot to stash extra code shortly.

The load uniform/temporary operations output only to a pipeline
register, which must be consumed by another op in the same instruction
later.
The current implementation delays the decision of who will consume this
result to until the scheduling step. If the consumer node is not able to
use the pipeline register, a mov node may have to be created, during the
scheduler step.
As part of the ppir scheduler simplification, and now that the ppir
scheduler supports pipeline register dependencies, this can be
simplified by always creating a single mov node outputting to a normal
register that can be used directly by all consumers.

The select operation relies on the select condition coming from the
result of the the alu scalar mult slot, in the same instruction.
The current implementation creates a mov node to be the predecessor of
select, and then relies on an exception during scheduling to ensure that
both ops are inserted in the same instruction.
Now that the ppir scheduler supports pipeline register dependencies,
this can be simplified by making the mov explicitly output to the fmul
pipeline register, and the scheduler can place it without an exception.
Since the select condition can only be placed in the scalar mult slot,
differently than a regular mov, define a separate op for it.

The ppir scheduler grew to be rather complicated and containing many
exceptions as it also has to take care of inserting additional nodes
when it is mandatory for nodes to be in the same instruction.
As such, the lima lowering and scheduling process can be difficult to
understand and maintain.
The ppir lowering step created nodes hoping that the scheduler would
notice the exception and do the right thing.
This proposal adds a simple refactor to the scheduler so that it places
nodes with pipeline registers in the same instruction.
With the scheduler handling this in a general way, it is possible to
create same-instruction dependencies by using pipeline registers during
the lowering stage.
This is simpler to maintain because now we can make these dependencies
explicit in a single place (lowering), and we can drop exceptions from
scheduling.
Reducing the complexity of the scheduler is also useful as preparatory
work to support control flow in ppir.
