[AssumptionCache] Remove incorrect assertion from `removeAffectedValues()` (#214524)
The assertion in `removeAffectedValues()` is trying to enforce that,
when we come to remove the affected values of a live assume call, each
affected value has a corresponding line in the cache. This may not be
the case if the assume call has been modified via a call to
`Use::set()`, as our value handles are only notified on deletion and
RAUW. We're not worried about this, though, as the cache is
conservative.
Remove this assertion and add a comment explaining why we may fail to
find.
[libc++] Collapse `optional<T&>` inheritance hierarchy (#215286)
Resolves #215185
- Since `optional<T>` and `optional<T&>` are decoupled, there wasn't
much reason to have a base class for `optional<T&>`, so we can simplify
it by inlining all of the base members and private functions into it
directly.
- This leaves us with the iterator base which now only exposes the
`iterator` type, since we can also directly inline `begin()` and
`end()`.

[Clang] Include libc wrappers for LLVM environment CUDA / HIP (#208084)
Summary:
These wrappers (although they are empty right now) are used to inform
the offloading runtime of the supported libc / libm functions available
on the device. We do not include these for the standard HIP path because
they conflict with the alreaedy present utilities, but with the
LLVM-only route we should be able to use them.
[modulemap] Exclude the z/OS string.h wrapper from LLVM_Utils (#215800)
8fce476c8122 (https://github.com/llvm/llvm-project/pull/167703) replaced
`llvm/Support/SystemZ/zOSSupport.h` with
`llvm/Support/SystemZ/zos_wrappers/string.h`, a wrapper that pulls in
the system header via `#include_next` and then redeclares `strsignal`
and `strnlen` with `asm` labels. It is only meant to be reachable on
z/OS, and `llvm/CMakeLists.txt` adds the directory to the include path
solely when `CMAKE_SYSTEM_NAME` matches OS390.
The header was never excluded from the module map, though.
`LLVM_Utils.Support` is an umbrella over `llvm/Support`, so building
that module textually includes the wrapper on every host. This surfaced
building the Swift compiler on Windows, where `<string.h>` resolves to
the UCRT header that already declares `strnlen` as `_ACRTIMP`, i.e.
`__declspec(dllimport)`:
```
error: cannot apply asm label to function after its first use

[MLIR][ROCm] Export runtime wrappers on Windows (#213046)
Export the ROCm runtime wrapper entry points when building
`mlir_rocm_runtime` as a Windows DLL.
Use `__attribute__((visibility("default")))` on other platforms.
## Motivation
`extern "C"` prevents C++ name mangling, but it does not add symbols to
a
Windows DLL export table. Consequently, `mlir-runner` can load
`mlir_rocm_runtime.dll`, but ORC cannot resolve its `mgpu*` entry
points.
CUDA, SYCL, Vulkan, and SPIR-V runtime wrappers already use explicit
Windows
export annotations. This applies the same approach to the ROCm runtime.

video: add V4L2 compat symbols for ffmpeg/opencv
Adds v4l2_std_id, struct v4l2_standard/v4l2_plane, VIDIOC_G_STD/S_STD/
ENUMSTD, V4L2_STD_NTSC*, the MPLANE capability flag, multiplanar types
(VIDEO_MAX_PLANES, v4l2_plane_pix_format, v4l2_pix_format_mplane,
V4L2_TYPE_IS_MULTIPLANAR), V4L2_PIX_FMT_JPEG/YUV411P/SN9C10X, and the
MPEG control class (V4L2_CID_MPEG_BASE, V4L2_CID_MPEG_VIDEO_B_FRAMES).
video(4) capture devices are digital-only and never expose these, but
ffmpeg's libavdevice/v4l2.c and opencv's cap_v4l.cpp both reference
them unconditionally. Fixes their build against sys/videoio.h.

[libc++] Guard container benchmarks on library availability (#215408)
Instead of using TEST_STD_VER, use FTMs or requires clauses to enable
benchmarks for some recent features like `append_range`. This is needed
since older versions of the library don't provide these features, so the
container benchmarks as a whole would fail to compile instead of just a
few methods being disabled.
[Support] Fix format_object streaming ambiguity in Objective-C++ mode (#215826)
Upstreams https://github.com/swiftlang/llvm-project/pull/13625.
Streaming a format_object writes it through a temporary lambda. Swift's
C++ interoperability enables block pointer conversions, which makes
`raw_ostream::operator<<(const void *)` a viable candidate alongside
`operator<<(function_ref<size_t(char *, size_t)>)`, so overload
resolution is ambiguous. This breaks the Swift compiler because it
contains Swift code that interoperates with C++ code that instantiates
this template.
Bind the lambda to an explicit function_ref before streaming so the
intended overload is selected unambiguously in every language mode.

[LLDB] Track tool dependencies in Makefile.rules (#215701)
Before b9225e860769 (Allow tests to share a single build)
lldbtest.makeBuildDir() would delete the build dir before building a
test, but the shared test builds no longer have that behavior. Neither
does the check-lldb target delete the entire test build dir before
running, so tests don't get rebuilt when one of the tools (for example,
clang) change.
This patch is one way to solve this, by adding all tools as explicit
dependencies to each rule in the shared Makefile.rules.
