[mlir][shard, mpi] Adding Shard/MPI reduce_scatter and simplification (#184189)
- introduces a simplify pass, which finds such patterns and replaces it
with the equivalent `reduce-scatter`
- promotes the test-pass `test-shard-optimizations` to a proper pass and adds
- folding allgather+allslice into reduce_scatter
- sanitizes the `shard.reduce_scatter` op
- adds a new `mpi.reduce_scatter_block` op
- lowers `shard.reduce_scatter` to MPI
- lowers `mpi-reduce_scatter_block` to llvm

[CIR] Fix unreachable block generation in EH flattening (#184268)
The previous EH CFG flattening implementation would sometimes create
dispatch handlers in unreachable blocks. This seemed OK until I started
implementing the code to lower the flattened CIR to an ABI-specific form
and those weren't getting updated.
This change fixes the flattening code to avoid generating unreachable
blocks.
[ELF] Add TargetInfo::initTargetSpecificSections hook (#184292)
so that we can move target-specific synthetic section creation from
createSyntheticSections into per-target initTargetSpecificSections
overrides. This reduces target-specific code in the shared
SyntheticSections.cpp. The subsequent commits (split from
https://github.com/llvm/llvm-project/pull/184057) will move these
target-specific classes to Arch/ files.
[CI][SPIRV][NFC] Remove unneccessary mkdir from workflow (#184353)
The `CMake` command does the `mkdir` automatically.

[libc] Various GPU allocator tweaks and optimizations (#184368)
Summary:
Some low-hanging fruit tweaks. Mostly preventing redundant loads and
unnecessary widening. Some fixes as well, like nullptr handling,
incorrect rounding, and oversized bitfields.
[Clang] Generate ptr and float atomics without integer casts (#183853)
Summary:
LLVM IR should support these for all cases except for compare-exchange.
Currently the code goes through an integer indirection for these cases.
This PR changes the behavior to use atomics directly to the target
memory type.
Reapply "[SPIRV][NFCI] Use unordered data structures for SPIR-V extensions (#184162)
Reapply https://github.com/llvm/llvm-project/pull/183567 with minor
changes.
Problem causing the revert was we couldn't use the enum in `DenseMap`
directly because of some `TableGen` limitations so I casted made the map
use the underlying type, but that caused some UB, so I
[fixed](https://github.com/llvm/llvm-project/pull/183769) the `TableGen`
limitation so now it just works.
Fix `assignValueToReg` function's argument (#184354)
Because of [PR#178198](https://github.com/llvm/llvm-project/pull/178198)
the argument changes for `assignValueToReg`.
This PR aiming at fixing M86k experimental target
NAS-139710 / 26.0.0-BETA.1 / Add nginx route for rwd (#18327)
This commit adds an nginx reverse proxy route at /rwd/ pointing to the
rwd service on 127.0.0.1:1700. Since rwd listens on TCP, nginx handles
the missing service gracefully — returning 502 when rwd is down without
affecting startup or other routes. Port 1700 is also registered as a
reserved system port to prevent conflicts.
