tests/sys/vfs: add ABI-root absolute symlink tests
Pin the overlay namei(9) uses for Linux ABI processes: a target under
the ABI root wins (PR 289739), a native-only target should retry from
the native root (PR 297426), an ENOENT past a resolved ABI target is
not retried, and the plain no-symlink native fallback is unchanged.
Skip without a Linux userland so CI stays green. The two native-only
cases use atf_expect_fail until the retry lands.

ARM: Remove cached TargetABI from ARMBaseTargetMachine (#226482)
This cannot account for the "target-abi" module flag, so
let the uses query that. ARMElfTargetObjectFile was the one user of
this value, so this failed to respect the module flag.

Mips: Properly account for target-abi in subtarget construction
Store the used ABI from the target-abi module flag and add it to the
subtarget map key, so the module flag is properly respected.

[AArch64] Reorganise perfect shuffle generation. NFC (#224526)
This adds a generatePerfectShuffle implementation for parsing through
the perfect shuffle tables, generating a list of ShuffleEntry's that
represent the sequence of shuffles that need to be performed. This is
intended to be a NFC as-is, allowing it to be reused in global isel and
extended in the future to handle shuffles that are not part of the
shuffle table. The number of instructions generated can also be used for
costing shuffles, as we do for immediate generation.
[LV] Add tests for wide induction wrap flags (NFC). (#226715)
Add tests for:
* inductions where the lane offsets may signed-overflow, even if the
scalar induction values do not,
* inductions whose increment does not directly update the phi, where the
increment's wrap flags do not apply to the induction,
* narrow inductions where the VF may exceed the signed maximum of the
induction type.

Pull PCI fixes from Bjorn Helgaas:
- Make BAR resize work even for devices where no upstream bridge is
visible to the OS, which fixes an amdgpu regression on SolidRun
HoneyComb, which doesn't expose Root Ports to the OS (Liz Fong-Jones)
- Omit bus properties in dynamic OF nodes when a bridge has no
subordinate bus, which fixes early boot hangs caused by NULL pointer
dereferences with CONFIG_PCI_DYNAMIC_OF_NODES enabled (Angel J)
- Disable enhanced atomics on AMD NBIO 7.7 and 7.11 to avoid silent
data corruption on 64-bit DMAs (Mario Limonciello)

[WebKit Checkers] Add built-in recognition for standard view types (#226350)
libc++ doesn't fully annotate `[[clang::lifetimebound]]` for all view
types. This results in false negatives in borrow checking.
Ultimately we need to fix this in libc++, but for now we can work around
the most common / most important false negatives. For example, borrow
checking can now check
for (auto& x : vector | std::views::reverse) { ... }

[libc++] Add static_assert diagnostics for LWG3133 named requirements (#212360)
Add a static_assert to both std::complex<T> and std::valarray<T>
requiring that T be a cv-unqualified object type that satisfies the
Cpp17DefaultConstructible, Cpp17CopyConstructible, Cpp17CopyAssignable,
and Cpp17Destructible named requirements, per the revised wording in
[numeric.requirements]. This mirrors the existing pattern already used
by std::optional<T>.
Non-_v (class-style) trait forms are used throughout so that the
assertion is well-formed even when <complex>/<valarray> are included in
C++03/11/14 mode.
Test coverage:
- A .verify.cpp for complex<T> and one for valarray<T>, each covering
six failure modes: cv-qualified types, and one type violating each of
the four named requirements individually.
