Basically every pass in NIR uses nir_ssa_def_rewrite_uses which calls
nir_instr_rewrite_src which is fairly complex because it handles all
sorts of non-SSA cases. Since we already know a priori that every
source written by nir_ssa_def_rewrite_uses is SSA, we can check new_src
once at the top of the function and cut out all that complexity.
While we're at it, we expose a new SSA-only nir_ssa_def_rewrite_uses_ssa
helper which takes an SSA def which avoids the one SSA check. It's also
more convenient 90% of the time.

Apart from the single additional marker field, these queries will now
use the same layout as all other drivers.
This should allow us to modify a single component to add an additional
register for new metrics.
v2: Capture the query beging registers in reverse order to ensure
timestamp is as close as possible from measured draw call.

When transitioning the oa-*.xml files from Gputop to IGT, we also had
to deal with a python2->3 transition. Unfortunately the implementation
dependent hash table ordering leaked into the XML files and so things
changed quite a bit.
This script reorders things from the old to the new order in the
existing files.

For all generations supported we had a layout describing what register
to store to implement a MI_RPC replacement.
This is because, on Gen12 we need to snapshot OAG registers to get
correct values for the perf equations. There, the MI_RPC instruction
captures OAR register which do not have all the information we need.

This will be useful when we implement queries using a series of MI_SRM
instead of MI_RPC.
Unfortunately on Gen12, the MI_RPC command sources values from the OAR
unit which has a similar series of register as the OAG unit but some
of the configuration of HW doesn't reach OAR so we have to snapshot
OAG manually instead.

Those are not part of the OA reports and need some additional

we need to emit MI_SRMs to record them.
Equations making use of those counters are not there yet, they will

Where it is safe to do so, avoid the generation of code to convert a
condition code into a boolean which is then tested to generate a
condition code. This is only done in uniform ifs, and only for condition
values that are SSA and only used once (in that if statement).

Changes:
- disallow NGG culling for GS, fast launch for tess using template args
(GS can't do NGG culling, tess can't do fast launch)
- skip checking current_rast_prim with tessellation
(bake the condition into ngg_cull_vert_threshold)
- use only 1 vertex count threshold for enabling NGG shader culling
to simplify it. I think it doesn't have a big impact. The threshold
computation depends on more parameters than just fast launch.

When a secondary command buffer is encountered, insert an event that
links to the new batch.
This commit leaves intel_measure timestamp buffer objects mmapped,
which is more efficient than mapping/unmapping several times. With
the BOs mapped at all times, timestamp buffers can be managed directly
by intel_measure, where it will iterate over timestamps of linked
secondary buffers.
With timestamp buffers managed by intel_measure, a more efficient and
accurate check for render completion can be moved into intel_measure
from anv/iris.
