[analyzer][NFC] Merge the class `LocationContext` into `StackFrame` (#198211)
This commit implements the final parts of the roadmap described in issue
#190973 by merging the class `LocationContext` into the class
`StackFrame` and replacing `LocationContext` with `StackFrame`
throughout the analyzer.
crashinfo: Create core.txt.last symlink
When saving a coredump, savecore(8) maintains .last symlinks for the
info and vmcore artifacts, but not for the crashinfo text report.
Make crashinfo(8) create the link, pointing at the current
core.txt.<bounds> file.
This makes /var/crash/core.txt.last track the same core dump as
info.last and vmcore.last.
[mhorne: I tweaked the submission, such that the link will be created as
soon as the core.txt.X file is generated; not only after a successful
report has been written.]

[offload] add SKIP_KNOWN_FAILURE unittest macro (#196275)
... and disable failing level-zero tests, to be reenabled once the
plugin is fully functional.
Here is the passrate for the level-zero plugin unit tests:
```
Total Discovered Tests: 645
Skipped: 74 (11.47%)
Passed : 571 (88.53%)

[AArch64][GlobalISel] Add support for pmul intrinsic (#198809)
Previously, pmul couldn't lower as there were neither any GlobalISel
patterns for the intrinsic, nor a GlobalISel node to allow use of the
SelectionDAG patterns.
Create a G_PMUL node linked to the SelectionDAG node 'clmul' (CarryLess
MULtiplication). Now the ISel stage of GlobalISel has suitable patterns
to lower the intrinsic.
FreeBSD: Make it possible to build openzfs.ko with sanitizers
Add make options which let one respectively compile the kernel modules
with the address sanitizer, memory sanitizer, and undefined behaviour
sanitizer enabled. This makes it much easier to run the ZTS with those
sanitizers enabled.

[flang][OpenMP] Lower target in_reduction for host fallback
Teach Flang lowering and MLIR OpenMP translation to carry
in_reduction through omp.target for the host-fallback path.
The translation looks up task reduction-private storage with
__kmpc_task_reduction_get_th_data and binds the target region's
in_reduction block argument to that private pointer, so uses inside the
region do not keep referring to the original variable.
The patch also preserves in_reduction operands in the TargetOp builder
path and ensures target in_reduction list items are mapped into the
target region when needed.
The device/offload-entry path remains diagnosed as not yet implemented.
[lit] Modernize ParserKind implementation using Python3 IntEnum (#199965)
`ParserKind` in `TestRunner.py` uses a detached dictionary
for suffix mapping, which is a Python 2 idiom. We can convert
the class to a Python 3 `IntEnum`. No change in behavior.
This PR is part of the "GSoC 2026: Improving lit" project.

[OMPT] Add callback for `omp_target_memset` calls (#194168)
OpenMP v6.0 added new enum values to `ompt_callback_target_data_op_t`
for communicating `memset` events. Add a corresponding callback
invokation to `omp_target_memset` calls.
Expand the tests to ensure correct behavior.

[DenseMap] Replace tombstone deletion with TAOCP 6.4 Algorithm R (#199615)
DenseMap uses quadratic probing with lazy deletion: an erased entry
becomes a tombstone, a third bucket state alongside empty and live that
every find/insert must inspect.
Switch to linear probing with backward-shift deletion (Knuth TAOCP 6.4
Algorithm R), similar to the SmallPtrSet change #197637. This removes
the tombstone state entirely.
In exchange, erase now relocates the following live entries to close the
hole, so it invalidates iterators and references other than the erased
one. For callers that cache pointers into the bucket array,
erase(Key, OnMoved) and erase(iterator, OnMoved) fire a callback once
per
shifted bucket, so fix-ups cost O(cluster) rather than O(NumEntries).
ValueHandleBase::RemoveFromUseList uses this to refresh each moved
handle's PrevPtr.
