The patch gives out the details of the znver2 scheduler model.
There are few improvements with respect to execution units, latencies and
throughput when compared with znver1.
The tests that were present for znver1 for llvm-mca tool were replicated.
The latencies, execution units, timeline and throughput information are updated for znver2.

Looking into sched model for that CPU ...

It makes more sense to print out the number of micro opcodes that are issued
every cycle rather than the number of instructions issued per cycle.
This behavior is also consistent with the dispatch-stats: numbers from the two
views can now be easily compared.

Summary:
# Overview
This is somewhat partial.
* Latencies are good {F7371125}
* All of these remaining inconsistencies //appear// to be noise/noisy/flaky.
* NumMicroOps are somewhat good {F7371158}
* Most of the remaining inconsistencies are from `Ld` / `Ld_ReadAfterLd` classes
* Actual unit occupation (pipes, `ResourceCycles`) are undiscovered lands, i did not really look there.
They are basically verbatum copy from `btver2`
* Many `InstRW`. And there are still inconsistencies left...
To be noted:
I think this is the first new schedule profile produced with the new next-gen tools like llvm-exegesis!
# Benchmark
I realize that isn't what was suggested, but i'll start with some "internal" public real-world benchmark i understand - [[ https://github.com/darktable-org/rawspeed | RawSpeed raw image decoding library ]].

{F7443905}
If we look at the `_mean`s, the time column, the biggest win is `-7.7%` (`Canon/EOS 5D Mark II/10.canon.sraw2.cr2`),
and the biggest loose is `+3.3%` (`Panasonic/DC-GH5S/P1022085.RW2`);
Overall: mean `-0.7436%`, median `-0.23%`, `cbrt(sum(time^3))` = `-8.73%`
Looks good so far i'd say.

Adding the baseline tests in a preparatory NFC commit,
so that the actual commit shows the *diff*.
Yes, i'm aware that a few of these codegen-based sched tests
are testing wrong instructions, i will fix that afterwards.

Before this patch, the SchedulerStatistics only printed the maximum number of
buffer entries consumed in each scheduler's queue at a given point of the
simulation.
This patch restructures the reported table, and adds an extra field named
"Average number of used buffer entries" to it.
This patch also uses different colors to help identifying bottlenecks caused by
high scheduler's buffer pressure.

Summary:
First off: i do not have any access to that processor,
so this is purely theoretical, no benchmarks.
I have been looking into b**d**ver2 scheduling profile, and while cross-referencing
the existing b**t**ver2, znver1 profiles, and the reference docs
(`Software Optimization Guide for AMD Family {15,16,17}h Processors`),
i have noticed that only b**t**ver2 scheduling profile specifies these.
Also, there is no mca test coverage.

Summary:
While that is indeed a quite interesting summary stat,
there are cases where it does not really add anything
other than consuming extra lines.
Declutters the output of D48190.
