[lldb][windows] switch to Python 3.11 for the non ARM64 release builds (#175796)
This patch is a follow up to
[RFC#89434](https://discourse.llvm.org/t/rfc-sync-python-versions-on-windows/89434).
Python 3.11 is the first official Python.org release to have an arm64
installer on Windows, which is why it's the version used to build the
toolchain on arm64 Windows. The x86 and x64 variants of the toolchain
both use Python 3.10 which can be confusing for users who get different
install dependencies based on their architectures.
This patch syncs all the required Pythons to install the toolchain, by
bumping the requirements to 3.11 for x86, x64 and arm64 Windows.
[libc++][test] Fix `constexpr` stdver. for tests for `find_if(_not)` (#176303)
Until C++20, `std::find_if(_not)` were not `constexpr`, so uses of
`TEST_CONSTEXPR_CXX17` make the test functions ill-formed, no diagnostic
required in C++17 mode.
The uses were introduced in 2b4b26ea84fd9c95d0ff25ce338c15ea5e74a4e4,
while the transformation looked incorrect - `TEST_CONSTEXPR_CXX20`
should be used instead.
Drive-by changes: Fix comments in both changed test files to match the
actually standardized wording.
[analyzer] Teach `unix.BlockInCriticalSection` about `std::scoped_lock` (#176134)
The checker knows that `std::lock_guard` and `std::unique_lock`
introduce critical sections, but doesn't know about the newer
`std::scoped_lock`.
[LIT][LLVM-STRINGS]Make stdin tests shell-consistent (#176139)
The fix updates the llvm-strings stdin lit tests to use `printf` instead
of `echo -n` when generating input via stdin.
The behavior of `echo -n` is not portable and varies across shells and
platforms, particularly on AIX where `/bin/sh` handles `-n` and escape
processing differently from GNU-compatible shells. This causes the tests
to fail despite correct llvm-strings functionality.
In contrast, `printf` has well-defined, POSIX-specified semantics and
provides consistent handling of newlines, escape sequences, and
non-printable characters. Using `printf` eliminates the dependency on
shell-specific `echo` behavior and makes the tests deterministic.
[clang] Fix options handling in ClangExtDefMapGen.cpp (#176116)
Also, remove some unused includes.
Fixes https://github.com/llvm/llvm-project/issues/176118
Now, running `clang-extdef-mapping` with no options results in the
following error message:
```sh
error: clang-extdef-mapping: Not enough positional command line arguments specified!
Must specify at least 1 positional argument: See: ./build/Debug/bin/clang-extdef-mapping --help
```
[LoopVectorize] Support vectorization of overflow intrinsics (#174835)
Enables support for marking overflow intrinsics `uadd`, `sadd`, `usub`,
`ssub`, `umul` and `smul` as trivially vectorizable.
Fixes #174617

[MLIR][shard] checking for correct&full sharding annotations (#176000)
Before trying to partition a block or operation, check that it is fully
annotated with `shard.shard` ops. This gives useful error messages
instead of random errors later on.
[mlir] Fix build after #175815 (#176332)

```
error: operands to ?: have different types ‘mlir::Operation::result_range {aka mlir::ResultRange}’ and ‘mlir::ValueRange’
return successor.isParent() ? getOperation()->getResults() : ValueRange();

lib/virtual_oss: don't (over)link to libsamplerate
These plugins require samplerate.h due to virtual_oss's int.h including
it, but don't use any symbols directly so don't link to the library.
Centralize adding the include path.

virtual_oss: build system tidying
general:
- find libsamplerate's headers in the temporary sysroot instead of
digging in the source tree.
- use LIBADD where possible
lib/virtual_oss:
- centralize SHLIBDIR define
- centralize include path for internal headers
- don't try to find libsamplerate directly in .OBJDIR
No functional changes.
