[DAGCombiner] Fold (or (seteq X, 0), (seteq X, -1)) to (setult (add X, 1), 2) (#192183)
This is the De Morgan dual of the existing fold:
(and (setne X, 0), (setne X, -1)) --> (setuge (add X, 1), 2)
The or-of-equalities version checks if X is either 0 or -1, which is
equivalent to (X+1) < 2 (unsigned). This reduces two comparisons and
an or to one add and one comparison.

[AsmPrinter] Fix AsmPrinterAnalysis::Result::invalidate to take PreservedAnalyses by const reference (#191742)
The invalidate method was taking PreservedAnalyses by value instead of
by const reference, causing an unnecessary copy on every invalidation
query. All other analysis invalidate methods in LLVM use const
reference.

[clang] implement CWG2064: ignore value dependence for decltype
The 'decltype' for a value-dependent (but non-type-dependent) should be known,
so this patch makes them non-opaque instead.
This patch also implements what's neceessary to allow overloading
on pure differences in instantiation dependence, making `std::void_t`
usable for SFINAE purposes.
This also readds a few test cases from da98651, which was a previous attempt
at resolving CWG2064.

[lld][MachO] Key branch-extension thunks on (referent, addend) (#191808)
TextOutputSection::finalize ignored branch relocation addends. Two call
sites branching to the same symbol with different addends therefore
collapsed onto a single thunk.
Key thunkMap on (isec, value, addend) so two call sites with different
addends get independent thunks. The addend is encoded in the thunk's
relocs and is zeroed at the call site after the callee is redirected to
the thunk. Thunk names carry a `+N` suffix when the addend is non-zero.
emulators/rpcs3: back to llvm19 after 7d6a0a090b03
Newer LLVM can break game compatibility thus discouraged upstream.
As RPCS3 no longer builds with Clang 19 use both llvm19 and llvm20.

CI: Disable ZIP file artifacts, update versions
The GH artifacts action now lets you disable auto-zipping your
artifacts. Previously, GH would always automatically put your
artifacts in a ZIP file. This is annoying when your artifacts
are already in a tarball.
Also update the following action versions
checkout: v4 -> v6
upload-artifact: v4 -> v7
download-artifact: v4 -> v8
Lastly, fix a issue where zfs-qmeu-packages now needs to power
cycle the VM.

Fix available space accounting for special/dedup (#18222)
Currently, spa_dspace (base to calculate dataset AVAIL) only includes
the normal allocation class capacity, but dd_used_bytes tracks space
allocated across all classes. Since we don't want to report free
space of other classes as available (we can't promise new allocations
will be able to use it), report only allocated space, similar to how
we report space saved by dedup and block cloning.
Since we need deflated space here, make allocation classes track
deflated allocated space also. While here, make mc_deferred also
deflated, matching its use contexts. Also while there, use
atomic_load() to read the allocation class stats.

packages: Fix build with libucl 0.9.3
In libucl 0.9.3, macros and includes are disabled by default when
creating a new UCL parser. This breaks the package build, which
relies on includes. Fix this by explicitly passing zero flags
to ucl.parser().
