[NewPM] Only add passes after optimized RegAlloc if a target enables it
The legacyPM allows for returning a boolean from
addRegAssignAndRewriteOptimized, and if set to false, some extra passes
at the end of addOptimizedRegAlloc are not added. Before this patch, the
NewPM would only omit adding these passes if an error was thrown, which
gets propagated all the way back up and prevents compilation.
This is necessary behavior for targets that do not perform register
allocation, like WebAssembly, that will otherwise crash in places like
MachineLICM.

[mlir][acc] Lower per-thread array reductions correctly (#210453)
Lowering an acc.reduction_accumulate_array to a per-element
gpu.all_reduce is only valid when each thread owns its own accumulator
copy. This was inferred from the memref's static size, which was wrong
for dynamically-shaped accumulators and for storage seen through
descriptor or strided views.
Per-thread accumulators that fit the local stack budget are materialized
in stack memory; anything larger, or gang-scoped, is materialized in
shared memory. Classify from that: a stack alloca (or a view over one)
within the budget is per-thread, a shared allocation is block-shared,
and a dynamically-shaped accumulator is classified from its par_dims.
Materialization and predication follow the same rule, and writes to a
privatization are recognized through views/casts so per-thread setup
runs on every owning thread.
[lldb] Avoid data race when clearing an OptionValue (#208471)
The clear function guarded by the internal mutex.
This happens when we have to threads one trying to set a value and the
other reseting the value.
The derived classes are forced to implement the `ClearImpl`. and base
`OptionValue` hold the mutex and calls `ClearImpl` on clear.
[NFC] [rtsan] Cleanup env for lit tests (#210395)
This matches the style of our other tests, and may make it easier for

NAS-141848 / 26.0.0-BETA.3 / Handle type-safe snapshot-task attachments in pool export/import (by creatorcary) (#19350)
Non-cascade `pool.export` crashed with
`'PeriodicSnapshotTaskQueryResultItem' object is not subscriptable`,
aborting the export after it had already disabled the pool's
shares/services and its snapshot tasks.
The export/import attachment loops iterate every delegate's `query()`
results and subscript them as dicts (`attachment['id']`).
[NAS-139294](https://ixsystems.atlassian.net/browse/NAS-139294) made
`pool.snapshottask` return type-safe Pydantic models, so the
snapshot-task delegate now yields model objects that aren't
subscriptable. Guard both call sites (`pool_/export.py` and
`pool_/import_pool.py`) to fall back to attribute access, matching the
fix already on master in
[#19278](https://github.com/truenas/middleware/pull/19278).

devel/cminpack: Update to 1.3.13
ChangeLog: https://github.com/devernay/cminpack/releases/tag/v1.3.13
* Fix a division by zero in covar1 when the Jacobian rank equals the number of
residuals (m == rank, e.g. square full-rank problems), which produced Inf/NaN
throughout the covariance matrix.
* Make the banded finite-difference branch of fdjac1 call the user function
with iflag=2, like the dense branch, fdjac2 and the FORTRAN version.
* Fix the USE_BLAS Newton correction in lmpar to use all n components (it was
truncated to the original Jacobian rank, giving a wrong step for
rank-deficient problems).
* Fix the jpvt memset size in the USE_LAPACK qrfac, and make the work-array
size checks in hybrd, hybrj, hybrd1, hybrj1 and lmdif1 overflow-safe (also in
the f2c versions).
* Guard a harmless transient infinity in dogleg for rank-deficient Jacobians
(also in the f2c version).

Summary:
Extension to https://github.com/llvm/llvm-project/pull/209770/, the
previous one did not cover all cases we search paths, it only did the
relative paths for a few cases. This adds it to the other case, should
be the same logic and motivation.
