[lldb] Add MSVC STL formatter for std::expected (#217243)
Pretty-print MSVC STL `std::expected<T, E>` and `expected<void, E>`.
Engaged values show `Value`; unexpected alternatives show `Unexpected`.
The anonymous union is walked the same way as `optional` so PDB debug
info still finds `_Value` / `_Unexpected`.
Tests: generic C++23 MSVC STL coverage for engaged, unexpected, void,
and reference cases using PDB debug info.
Part of #24834

libusb: Avoid signed integer overflow UB
Instead, just reset next_callback_id to 1 at INT_MAX. The potential for
duplicate callback IDs remains.

multimedia/butt: update 1.45.0 -> 1.47.0, pet repology
- Fix possible corruption when recording .wav files

[VPlan] Expand negated add operands as a subtract in VPSCEVExpander. (#215253)
Update VPSCEVExpander to try to expand adds of negative values as
subtract, instead of adding the negated operand. This matches IR
SCEVExpander behavior and improves expansions slightly.
It also avoids regressions when expanding more expressions.

[clang][win] Fix __global_delete breaking __attribute__((used)) (#217753)
The `__empty_global_delete` fallback introduced in #209585 was marked
used via `llvm::appendToUsed()`, which creates a global named
"llvm.used" during codegen. `CodeGenModule::emitLLVMUsed()` later
unconditionally creates its own global of that same name at end-of-TU,
so the name collision renamed the latter to "llvm.used.1" -- a name LLVM
ignores. The result was that every `__attribute__((used))` global in the
TU silently lost its used semantics whenever a `__global_delete` wrapper
was emitted, letting those symbols be dropped.
Mark the fallback used via `CodeGenModule::addUsedGlobal()` instead, so
it joins the single llvm.used that `emitLLVMUsed()` emits.
`emitLLVMUsed()` runs well after `emitGlobalDeleteForwardingBodies()` in
`Release()`, so the fallback is still recorded in time.
Fixes a regression reported on #209585.
makefs: Fix atime tests on MS-DOS (FAT) file systems
On FAT file systems, access time has a resolution of 1 day, so it is
really the access date.
Strip the time component from the epoch timestamp in order to check the
access time.

makefs: zfs: Allow the path vdev property to be set
This allows specifying custom vdev paths (such as GPT labels like
/dev/gpt/...) when creating ZFS filesystem images via makefs(8), rather
than defaulting to /dev/null.

[SSAF][EntityPointerLevel] Add an intermediate data structure DeclPointerLevel
A DeclPointerLevel differs from an EntityPointerLevel only in that it
retains the AST Decl node instead of abstracting it to an Entity. The
AST node carries more information, such as types, that can be used by
extractors before converting DeclPointerLevels to EntityPointerLevels.
E.g., PointerFlowExtractor can use it to compute the upper bound on
pointer levels for an entity. It is needed for fixing the bug reported
in rdar://183529483.
First step for:
