sysutils/kopia: Update 0.23.1
- Switch from GO_BUILDFLAGS to GO_LDFLAGS
- Use BuildInfo=${HOSTARCH}-portbld-${OPSYS:tl}-${OSREL:R} instead of date
for better reproducibility.

[llvm] Replace unordered_{map,set} with Dense{Map,Set} (#202222)
std::unordered_map is slow. The remaining uses are pointer stability,
key spanning the full value range, or huge pair<key,value>. After
PR #201281 DenseMap no longer reserves sentinel keys, so more of these
maps can switch.

mvc: DescriptionField: disable special and newline characters
This is only cosmetic and since the description is only used as a
label and not a note block this is fine (and could be overwridden
by the model if needed).
[MLIR] Adopt HasAncestor trait in omp.workshare.loop_wrapper and emitc.get_field (#197911)
Following #195447 which added the `HasAncestor` trait, replace the
ancestor-existence checks in two ops:
- `omp.workshare.loop_wrapper`
- `emitc.get_field`
games/openenroth: introduce some minor improvements and fixes
- Reflect currently required C++ standard (23) in the USES line
- Convert GH_ACCOUNT/GH_PROJECT/GH_TAGNAME/GH_SUBDIR lists into
GH_TUPLE which is shorter, more blame-friendly and thus easier
to maintain (assess changes)
- Depend on `math/fast_float' implementation from the ports
- Try to unbreak the build against Clang 21.1.8 by initializing
const pointer and explicitly invoking operator bool() when
asserting unique_ptr

[Codegen] Avoid duplicate subranges for unused lanes (#204091)
Splitting registers in `RenameIndependentSubregs` requires inserting
`IMPLICIT_DEF` to ensure definition of the new register on all paths.
The existing logic for handling unused lanes would create duplicate
subranges if multiple predecessor blocks exist, causing the machine
verifier to fail.
This change ensures that only a single subrange is created for the
unused lanes which is then updated with additional segments in the
following iterations.
This fixes https://github.com/llvm/llvm-project/issues/197733.

[Clang][OpenCL] Add OpenCL 3.1 language version (#204043)
OpenCL 3.1 was recently added to spec in
https://github.com/KhronosGroup/OpenCL-Docs/commit/9fff1a87a975
This PR adds version 3.1 to clang support, including frontend flag
`-std=cl3.1` (and its alias `-std=CL3.1`).
Updated release note.
A few extensions are promoted to 3.1 core. They'll be handled in
follow-up PRs.

[RFC][IR] Extract AMDGPU-specific verification logic into `VerifierAMDGPU.cpp`
`Verifier.cpp` is large and already mixes generic IR verification with
target-specific checks. We also have a growing amount of AMDGPU verifier logic
downstream, which would all end up in the same file if we don't address this,
and that is not ideal.
This patch extracts AMDGPU-specific verification logic into a separate
`VerifierAMDGPU.cpp` file, with shared infrastructure (`VerifierSupport`) moved
into `VerifierInternal.h`.
This is purely a code organization change, not a target-dependent IR verifier.
All checks remain compiled and linked into `LLVMCore` regardless of the target
triple. The extracted functions are called unconditionally at well-defined
extension points in `Verifier.cpp`, and each function internally gates on
target-specific conditions (for example, triple checks or intrinsic IDs) as
needed. The file is strictly limited to AMDGPU-specific IR constructs (amdgcn
intrinsics, AMDGPU module flags, etc.), and does not contain generic IR rules
that vary by target.

[LoongArch] Add DAG combine for widening shift-left (#202602)
Add DAG combines to recognize vector widening left-shift idioms and
lower them to VSLLWIL instructions.
The following pattern is matched for both signed and unsigned variants:
```
SEXT/ZEXT(Low-Half-Lanes(vec)) << Imm
```
This covers the following instructions:
```
LSX: VSLLWIL.H.B, VSLLWIL.W.H, VSLLWIL.D.W
VSLLWIL.HU.BU, VSLLWIL.WU.HU, VSLLWIL.DU.WU
LASX: XVSLLWIL.H.B, XVSLLWIL.W.H, XVSLLWIL.D.W
XVSLLWIL.HU.BU, XVSLLWIL.WU.HU, XVSLLWIL.DU.WU
```
[RDF] Replace unordered_map with DenseMap. NFC (#204280)
std::unordered_map is slow. Switch DefStackMap and RefMap to DenseMap.
erase-while-iterating loops become DenseMap::remove_if.
