nir/algebraic: Use value range analysis to eliminate tautological compares not used by if-statements
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).
v2: Reorder and add whitespace to make the relationship between the
patterns more obvious. Suggested by Caio.

nir/range-analysis: Rudimentary value range analysis pass
Most integer operations are omitted because dealing with integer
overflow is hard. There are a few things that could be smarter if there
was a small amount more tracking of ranges of integer types (i.e.,
operands are Boolean, operand values fit in 16 bits, etc.).
The changes to nir_search_helpers.h are included in this patch to
simplify reordering the changes to nir_opt_algebraic.py.
v2: Memoize range analysis results. Without this, some shaders appear
to get stuck in infinite loops.
v3: Rebase on many months of Mesa changes, including 1-bit Boolean
changes.
v4: Rebase on "nir: Drop imov/fmov in favor of one mov instruction".
v5: Use nir_alu_srcs_equal for detecting (a*a). Previously just the SSA
value was compared, and this incorrectly matched (a.x*a.y).
v6: Many code improvements including (but not limited to) better names,
more comments, and better use of helper functions. All suggested by
Caio. Rework the handling of several opcodes to use a table for mapping
source ranges to a result range. This change fixed a bug that caused
fmax(gt_zero, ge_zero) to be incorrectly recognized as ge_zero.
Slightly tighten the range of fmul by recognizing that x*x is gt_zero if
x is gt_zero. Add similar handling for -x*x.
v7: Use _______ in the tables as an alias for unknown. Suggested by
Caio.

iris: Fix bad external BO hash table and zombie list interactions
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.

iris/bufmgr: Move iris_bo_reference into hash_find_bo, rename it
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.

lima/ppir: simplify load uni/temp op lowering and scheduling
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.
