[CIR] Split CIR_UnaryOp into individual operations (#185280)
Split the monolithic cir.unary operation (which dispatched on a
UnaryOpKind enum) into four separate operations: cir.inc, cir.dec,
cir.minus, and cir.not.
Changes:
- Add CIR_UnaryOpInterface with getInput()/getResult() methods
- Add CIR_UnaryOp and CIR_UnaryOpWithOverflowFlag base classes
- Define IncOp, DecOp, MinusOp, NotOp with per-op folds
- Add Involution trait to NotOp for not(not(x)) -> x folding
- Replace createUnaryOp() with createInc/Dec/Minus/Not builders
- Split LLVM lowering into four separate patterns
- Split LoweringPrepare complex-type handling per unary op
- Update CIRCanonicalize and CIRSimplify for new op types
- Update all codegen files to use bool params instead of UnaryOpKind
- Remove CIR_UnaryOpKind enum and old CIR_UnaryOp definition
Assembly format change:
cir.unary(inc, %x) nsw : !s32i, !s32i -> cir.inc nsw %x : !s32i
cir.unary(not, %x) : !u32i, !u32i -> cir.not %x : !u32i
[CIR] Split CIR_UnaryOp into individual operations
Split the monolithic cir.unary operation (which dispatched on a
UnaryOpKind enum) into four separate operations: cir.inc, cir.dec,

This follows the same pattern used when cir.binop was split into
individual binary operations (AddOp, SubOp, etc.).
Changes:
- Add CIR_UnaryOpInterface with getInput()/getResult() methods
- Add CIR_UnaryOp and CIR_UnaryOpWithOverflowFlag base classes
- Define IncOp, DecOp, MinusOp, NotOp with per-op folds
- Add Involution trait to NotOp for not(not(x)) -> x folding

[clang-tidy] Add redundant qualified alias check (#180404)
Introduce `readability-redundant-qualified-alias` to flag identity type
aliases that repeat a qualified name and suggest using-declarations when
safe. The check is conservative: it skips macros, elaborated keywords,
dependent types, and templates. `OnlyNamespaceScope` controls whether
local/class scopes are included (default `false`).

[clang][Driver][Darwin] Optionally use xcselect to find macOS SDK (#119670)
This is a scaled down version of https://reviews.llvm.org/D136315.
The intent is largely the same as before[^1], but I've scaled down the
scope to try to avoid the issues that the previous patch caused:
- the changes are now opt-in based on enabling `CLANG_USE_XCSELECT`
- this only works when targeting macOS on a macOS host (this is the only
case supported by `libxcselect`[^2])
- calling `libxcselect` is done only when the target is `*-apple-macos*`
to avoid breaking many tests
Another reason to leave this as opt-in for now is that there are some
bugs in libxcselect that need fixing before it is safe to use by default
for all users. This has been reported to Apple as FB16081077.

[libc++][Android] Update Compiler for Android CI (#186531)
Upgrade Android compiler from r563880 to r584948b because libc++ does
not support LLVM 20 anymore
Fix alert deserialization crash on upgrade
This commit fixes an issue where middleware won't start when a system
is upgraded to latest nightlies because the recent alerts mypy refactor
changed alert args format (moving fields from `key` into required
dataclass fields in `args`). Pre-existing alerts
in `system_alert` have the old format and crash during deserialization
at startup. The migration deletes the affected rows; all are ephemeral
and regenerated by their alert sources within 60 seconds.
[CIR] Add Pure trait to IsFPClassOp
IsFPClassOp is a pure classification check on a floating-point value
with no memory effects. Mark it Pure to enable DCE and other
optimizations.
re(4), rge(4): improve Realtek driver man pages
Add D-Link DGE-530(T) and Killer E2600 to the re(4) HARDWARE list.
Both are supported by the driver but were missing from the man page.
Also add cross-references between re(4) and rge(4) in SEE ALSO,
as both are Realtek NIC drivers.

Clean-up / consolidation of m68k bus error / address error handling
code. This is not a very radical change for most m68k platforms,
since they were using a version of this re-factored code already via
an #include directive in locore.s. Now, however, the bus error handlers
are split into CPU "generation"-specific files, and brought into the
kernel via the CPU options in the kernel config file (the goal being
to reduce boilerplate in each locore.s).
The more notable changes:
- amiga and atari no longer have their own copy of each handler, and
some of their local tweaks have been folded into the shared code.
- sun2's bus error handling code has been re-factored into a shared
buserr_10.s to facilitate support for other 68010-based systems (all
of which have their own custom MMU).
- sun3's bus error handling code has been re-refactored into the
shared buserr_2030.s. The Sun3-specific MMU handling is treated
just like the HP-specific MMU handling that was already there.
This additional #ifdef is a small price to pay for more code sharing.
- sun3x now also uses the shared buserr_2030.s rather than an identical
