rpminspect: disable abidiff inspection
We need to disable abidiff due to huge memory consumption, leading to
OOM kill of the whole rpminspect run.

Fix alternatives handling
This implements multiple fixes to the handling of llvm-config
alternatives:
* Increase alternative priority for new versions. Otherwise we'll
give all versions the same priority. The new one will be something
like 2064 for the 64-bit LLVM 20 llvm-config binary.
* Remove old llvm-config-64/llvm-config-32 alternative. This is
only needed once, so suppress the error.
* Do not remove no longer used llvm-config-64/32 in postun scriptlet.
Instead remove the llvm-config in install_bindir. However, now
that the path will be the same for compat and non-compat LLVM,
only do this on uninstall, not on upgrade.

Use libdir suffix in versioned prefix as well
Use the lib/lib64 distinction for the versioned prefix, to avoid
a mismatch with the default prefix. This means that the versioned
prefix now has libraries in /usr/lib64/llvmN/lib64.
This should fix the issue https://src.fedoraproject.org/rpms/llvm/pull-request/446
ran into. This would also be needed if we wanted to switch to
installing into libexec.

Add task-taskwait-nested test to LIT_XFAIL on ppc
This test fails on ppc, so add it to the XFAIL list like the other
similar tests. It would be better to fix the root cause, but in the
meantime, add it to XFAIL to unblock the snapshot builds.

Invert symlink direction
This is an alternative to:
https://src.fedoraproject.org/rpms/llvm/pull-request/439.
Instead of undoing the prefix change completely, this instead inverts
the direction of the symlinks: The non-compat package ships all the
files in the default prefix, but has symlinks from the versioned
prefix to the default prefix.
The implementation approach is to install everything into the
versioned prefix first (keeping things unified between compat and
non-compat build initially) and to then move and symlink in
post-processing.
The llvm-config setup here stays the same as it currently is,
with llvm-config executables being installed in the versioned
prefix, while the one in the default prefix is managed by
alternatives. This patch does not fix the issues with alternatives
handling, we'd apply https://src.fedoraproject.org/rpms/llvm/pull-request/417
on top of this patch for that.
Fixes https://bugzilla.redhat.com/show_bug.cgi?id=2365079.

Previously, the build used to pass because llvm-test-suite requires
llvm. As we restrict the execution of the perf comparison on snapshot
builds, llvm-test-suite won't be installed anymore.

Allow openmp tests to re-run two times
Once https://github.com/llvm/llvm-project/pull/141851 is merged, we can
use the new lit-option `--max-retries-per-test=<POSTIVE_INT>` in order to
re-run openmp tests.
This change makes use of this option and configures it, so that openmp
tests are re-run 4 times if needed. To prove that this works, we no
longer filter out the flaky tests.
Once https://github.com/llvm/llvm-project/pull/142413 lands we can add
`--show-attempts-count` to show how many attempts were actually needed.

Bring in PGO (Profile Guided Optimization)
This enable PGO (Profile Guided Optimization) on Fedora >=41 and RHEL >= 9 for
non x86 machines.
This is a four step process:
1. We use the system clang compiler to build an instrumented version of LLVM.
The first build of LLVM is rather small because it only features the native
subset of targets to build (`LLVM_TARGETS_TO_BUILD=Native`) and no tests or
whatsoever is built.
2. We run a special `cmake` target (`generate-profdata`) that collects profile
data information. Eventually this information is also packaged as
`llvm-pgo.profdata`.
3. We feed the profile information into another final build of LLVM that gets
packaged later.
4. If we are on a platform that provides the `llvm-test-suite` package we run a
performance comparison of the system compiler against the PGOed compiler.
This is meant as a sanity check. We package the output of that comparison (if
available) as `results-system-vs-pgo.txt`. The criteria to run this
performance comparison is influenced by the `run_pgo_perf_comparison` global.
For snapshot builds we even run the comparison for RHEL platforms where
usually the `llvm-test-suite` is not available. There we provide it through
this COPR project:
[@fedora-llvm-team/llvm-test-suite](https://copr.fedorainfracloud.org/coprs/g/fedora-llvm-team/llvm-test-suite/).
We pass `--build-id=sha1` to lld when building final stage with PGO LLD uses
"fast" as the algortithm for generating build-id values while ld.bfd uses "sha1"
by default. We need to get lld to use the same algorithm or otherwise we end up
with errors like thise one:
```
build-id found in [...]/usr/lib64/llvm21/bin/llvm-debuginfod-find too small
```
NOTE: We decided to not do a bootstrap build of clang.
NOTE: To disable PGO change `%bcond_without pgo` to `%bcond_with pgo` in the one
line where it is conditionally defined. All the relevant changes are
build-condition fenced with `%if %{with pgo}`.

Disable offload on ppc64le on RHEL <= 9
1. Add a conditional in order to control the build of offload libraries.
2. Use this conditional when building for %{ix86}.
3. Disable the build of offload for ppc64le on RHEL <= 9 due to the lack
of support for the IBM long double format. As offload starts to
depend more on libc on LLVM 21, it started to depend on long double
code that never supported the IBM long double format.

Do not create symlinks on i686
Currently, it's not possible to install llvm-devel.i686 and
llvm-devel.x86_64 at the same time, breaking multilib support.
The reason is that binary symlinks between the two packages
conflict, and unlikely for file conflicts, dnf treats these as
an error.
Fix this by not shipping any symlinks in the default prefix on
i686. This means that i686 packages only ship the contents of
/usr/lib/llvmN. This allows conflict-free co-installation with
the x86_64 packages.
I have opted to drop *all* of the symlinks in the default prefix
on i686, but this is not strictly necessary. E.g. keeping lib
symlinks should be fine. But I think it's cleaner to just say
that i686 has everything in the llvm prefix only, rather than
trying to be more precise.

Remove alternatives support for llvm-config
llvm-config and llvm-config-N are now plain symlinks to the
llvm-config in the llvm prefix, just like all other binaries.
In order to remove the old alternaties setup, I'm running
alternatives --remove-all in a pre scriptlet. This should remove
the old alternatives before the new symlink directly owned by
the package is added.
This also fixes https://bugzilla.redhat.com/show_bug.cgi?id=2361779.
