[LifetimeSafety] Handle escape through assignment to global storage (#181646)
This PR allows for modelling escape of parameters to global storage, and
dangling global storage.
Change summary:
1. Created `GlobalEscapeFact` as a subclass of `OriginEscapesFact`
2. Emit a `GlobalEscapeFact` for all origins with global-storage that
remain live at function exit.
3. Integrated into warning reporting as necessary, introducing the
groups `-Wlifetime-safety-dangling-global` and
`-Wlifetime-safety-dangling-global-moved`
4. Wrote sema tests for escape to a variety of global storage locations.
[lldb] Use AppendMessageWithFormatv instead of AppendMessageWithFormat (#185012)
When the message ends with a newline. ...WithFormatv adds a newline
automatically.
Note that the ":x" style is lower case hex with 0x prefix. (see
llvm/include/llvm/Support/FormatProviders.h)
This change does not change uses where multiple chunks are emitted to
one line, or the message has embedded newlines. I want to deal with
these more complex cases later.
This is round 3 of N doing this, converting a few files at a time.

[libc++] Reduce the amount of formatter code included in <vector> (#178683)
`formatter::parse` and `formatter::format` only have to accept
`basic_format_parse_context` and `basic_format_context` respectively,
which are only guaranteed to be provided via `<format>`. This allows us
to only declare the functions for `formatter<bool>` in `<vector>` and
define them if `<format>` is included. This reduces the amount of time
it takes to parse `<vector>` by ~15% on my system.

[MC] Rename PrivateGlobalPrefix to InternalSymbolPrefix. NFC (#185164)
The "private global" terminology, likely came from
llvm/lib/IR/Mangler.cpp, is misleading: "private" is the opposite of
"global", and these prefixed symbols are not global in the object file
format sense (e.g. ELF has STB_GLOBAL while these symbols are always
STB_LOCAL). The term "internal symbol" better describes their purpose:
symbols for internal use by compilers and assemblers, not meant to be
visible externally.
This rename is a step toward adopting the "internal symbol prefix"
terminology agreed with GNU as
(https://sourceware.org/pipermail/binutils/2026-March/148448.html).
Remove custom Rx A-MPDU reordering code from iwx(4).
The equivalent code was deleted from iwlwifi in 2023. It is only needed for
iwm 9k devices running with multiple Rx queues. AX200 and later devices do
Rx reordering in firmware and provide flags the driver can check to avoid
sending duplicate frames up the stack.

[libc++] Fix strict aliasing violation for `deque::const_iterator` (#136067)
When the allocators use fancy pointers, the internal map of `deque`
stores `FancyPtr<T>` objects, and the previous strategy accessed these
objects via `const FancyPtr<const T>` lvalues, which usually caused core
language undefined behavior. Now `const_iterator` stores `FancyPtr<const
FancyPtr<T>>` instead of `FancyPtr<const FancyPtr<const T>>`, and ABI
break can happen when such two types have incompatible layouts.
This is necessary for reducing undefined behavior and `constexpr`
support for `deque` in C++26, and I currently don't want to provide any
way to opt-out of that behavior.
For `iterator`, the current strategy makes it store
`FancyPtr<FancyPtr<T>>`. But it would make more sense to also store
`FancyPtr<const FancyPtr<T>>` because we never modify the map via
`iterator`.
For some pathological combinations of allocators and fancy pointers, the

[ORC] Add WaitingOnGraph record / replay facilities. (#185275)
WaitingOnGraph is critical to the performance of LLVM's JIT (see e.g.
https://github.com/llvm/llvm-project/issues/179611), and these facilities will
make it easier to capture and investigate test cases, and build a performance
regression suite.
WaitingOnGraph::OpRecorder provides an interface for classes that want to
capture the essential WaitingOnGraph operations: simplify-and-emit, and fail.
WaitingOnGraph::simplify and WaitingOnGraph::fail now take an optional
OpRecorder pointer.
WaitingOnGraphOpStreamRecorder (WaitingOnGraphOpReplay.h) is an OpRecorder
implementation that serializes operations to a line-oriented text format on a
raw_ostream. WaitingOnGraphOpReplay provides types and utilities for iterating
over and replaying recorded operations. readWaitingOnGraphOpsFromBuffer returns
an iterator range over the ops in a serialized buffer.
The new ExecutionSession::setWaitingOnGraphOpRecorder method can be used to
