[mlir-c] Reapply Add ConversionTarget dynamic legality C API (#207104) (#207253)
Fixes LeakSanitizer failure from #206161 (reverted in #207104);
`mlirFreezeRewritePattern` moves contents out of the `RewritePatternSet`
but does not free the container (passed by value in the C API), so the
allocation from `mlirRewritePatternSetCreate` was never freed (add
`mlirRewritePatternSetDestroy(patterns)` after freezing).
[libc++] Base string's alignment on __STDCPP_DEFAULT_NEW_ALIGNMENT__ (#171785)
This allows users to influence how much we overalign `string`s
allocations and tune it to the new/delete implementation via
`-fnew-alignment`. If we don't have `__STDCPP_DEFAULT_NEW_ALGINMENT__`
or we're not using `std::allocator`, we default to an alignment of
`sizeof(void*)`.
[ELF] Precompute orphan output section names in parallel. NFC (#207321)
addOrphanSections computes getOutputSectionName serially for every live
orphan section. Without --emit-relocs/-r, the name is a pure function of
the section: precompute the names with a parallelFor.

misc/auto-tempo: Manage Jira Tempo Timesheets worklogs from a text file
AutoTempo manages Jira worklogs through the Tempo Timesheets REST API
using a simple, version-controllable text file.
It can generate a monthly worklog template pre-populated
with working days, expand keyword shortcuts and recurring entries
defined in config.toml, validate daily totals, and apply worklogs
idempotently to Jira. A helper can draft worklogs from local
git commit history.
Targets Tempo Timesheets on Jira Server/Data Center;
authentication uses a Jira personal access token.
The tool is run from a directory containing a config.toml file.

[DAGCombiner] Reassociate chains of vector reductions (#206471)
`DAGCombiner::reassociateReduction` already folds a single
`add(vecreduce(x), vecreduce(y)) -> vecreduce(add(x, y))`, and the
balanced-tree form `add(add(vecreduce(a), b), add(vecreduce(c), d))`.
It does not, however, handle a linear chain of reductions like the one
SLP emits for x264's SAD:
```
add(reduce(X0), add(reduce(X1), add(reduce(X2), acc)))
```
Only the innermost pair can ever be merged; the cascade breaks and every
reduction survives to lowering, giving one `vredsum` (or one `uadalp` step,
etc.) per term.
This PR adds a third form to `reassociateReduction`:

[clang][ssaf] Add `MultiArchSharedLibrary` data structure (#206854)
This change introduces `MultiArchSharedLibrary` data structure that wraps per-architecture `LUSummaryEncoding` members. This is the SSAF analogue of a fat shared library. The overall design mirrors the existing `MultiArchStaticLibrary` design: each member identifies the same logical library built for a different target triple. Support for constructing and consuming this object will be added in a future PR.

[RISCV] Cost legal interleaved memory ops correctly for code size (#207162)
This doesn't yet handle interleaved memory ops with a factor > 8 or with
a gap mask, that still needs to be handled below.
[ELF] Parallelize demoteSymbolsAndComputeIsPreemptible (#207310)
Each symbol's demotion and isPreemptible bit is independent.
Linking clang release is 1.02x as fast on an x86-64 machine.
lit: improve long path support on Windows (#207250)
This pull request improves Windows path handling in the
`llvm/utils/lit/lit` utilities by introducing and applying an `extended`
function to correctly format file paths for Windows APIs, especially for
long paths and UNC paths. The changes ensure that file operations such
as removal and redirection work reliably on Windows systems.
**Windows path handling improvements:**
* Added an `extended` function in both `InprocBuiltins.py` and
`ShellEnvironment.py` to convert paths to the extended-length format
required by Windows, handling both regular and UNC paths.

* Applied the `extended` function to file removal operations in
`InprocBuiltins.py`, ensuring paths are properly formatted before
deletion, which helps avoid issues with long or special Windows paths.
* Used the `extended` function for redirected file paths in
`ShellEnvironment.py`, ensuring that redirections to files handle
Windows path limitations correctly.

[RISCV] Fix multiline RUN line in fixed-vectors-lmul-max.ll. NFC (#207309)
llvm-lit failed to parse the RUN line because we were missing a \ and a
second
RUN on the line below. The codegen has changed in the meantime but
because it
never parsed, llvm-lit always treated this test as passing.
[libc++] Use _LIBCPP_NO_UNIQUE_ADDRESS for the new vector layout (#207149)
