[X86] AMD Piledriver (BdVer2): major cleanup (mainly inverse throughput)
I've started this cleanup more several times now, but got sidetracked
elsewhere, e.g. by llvm-exegesis problems. Not this time, finally!
This is mainly cleaning up the inverse throughput values,
and a few latencies/uops, based on the llvm-exegesis measured values.
Though this is not complete by any means,
there's certainly more cleanup to be done.
The performance numbers (i've only checked by RawSpeed benchmark) aren't
really surprising - overall this *slightly* (< -1%) improves perf.

[llvm-mca][scheduler-stats] Print issued micro opcodes per cycle. NFCI
It makes more sense to print out the number of micro opcodes that are issued
every cycle rather than the number of instructions
[llvm-mca][scheduler-stats] Print issued micro opcodes per cycle. NFCI
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.

[X86][BdVer2] Fix loads/stores throughput for Piledriver (PR39465)
There are two AGU units, and per 1cy, there can be either two loads,
or a load and a store; but not two stores, or two loads and a store.
Additionally, loads shouldn't affect the store scheduler and vice versa.
(but *should* affect the PdEX scheduler.)
Required rL346545.

AMD BdVer2 (Piledriver) Initial Scheduler model
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 ]].

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.

[NFC][X86] Baseline tests for AMD BdVer2 (Piledriver) Scheduler model
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.
