Revert "[LifetimeSafety] Detect iterator invalidation through container aliases" (#195702)
This introduces unintended side effects and causes downstream crashes,
so reverting for now.

[lldb-dap] Fix core file stop reason overridden to "entry" (#195352)
# Summary:
There's a behavior change on core file stop reason
It used to report the actual crash (stop) reason:
- reason: "exception" (reflecting the actual crash signal/exception)
- description: crash signals, eg."signal SIGSEGV"
However, the stopped event now always reports:
- reason: "entry"
- The crash reason is lost
## Root Cause
1. `bd0efcaa34b1` (Oct 31, 2025) — "[lldb-dap] Correctly trigger 'entry'
stop reasons"
This commit changed CreateThreadStopped in `JSONUtils.cpp`:
Changed `body.try_emplace("reason", "entry")` to `body["reason"] =
"entry"`, and this will overwrites it unconditionally.

[lldb] Use (_d).pyd as Python extension suffix on Windows (#195262)
The current Windows x86_x64 installer ships a `_lldb.abi3None` in
`lib\site-packages\lldb\native`. This will cause errors when trying to
import LLDB in Python.
We always use `.abi3{SHLIB_SUFFIX}` as the Python extension suffix in
`get-python-config.py`. On Windows(-msvc), this won't result in the
correct path. `SHLIB_SUFFIX` is not defined there.
The recognized extensions are:
```console
> python -c "import importlib.machinery;print(importlib.machinery.EXTENSION_SUFFIXES)"
['.cp314-win_amd64.pyd', '.pyd']
> python_d -c "import importlib.machinery;print(importlib.machinery.EXTENSION_SUFFIXES)"
['_d.cp314-win_amd64.pyd', '_d.pyd']
```
The first one is equal to `sysconfig.get_config_var("EXT_SUFFIX")`.

[SelectionDAG] Look through FREEZE in getCopyToRegs when checking isZExtFree (#195285)
When a narrow load i8 or i16 is frozen and its value crosses a basic
block, `getCopyToRegs` emits `any_extend` instead of `zero_extend`
because `isZExtFree` can't see through the `ISD::FREEZE` node.
Example: https://godbolt.org/z/MYvjq8vPM contains an redundant `and w11,
w11, 0xff`
```
ldrb w11, [x10], #1
cmp w11, #32
b.lo .LBB0_1
and w11, w11, #0xff
```
Fix this by passing the incoming node to the freeze to `isZExtFree`
instead.
[mlir][acc] Introduce privatization operations for codegen (#195273)
This change adds codegen-oriented operations for representing
private-variable storage and materializing the storage that a particular
parallel execution actually uses.
The two operations are meant to be used together:
- acc.privatize introduces an abstract handle for the privatized
storage,
including the parallel levels that determine the ultimate size of the
storage needed. Which parallel levels apply can be stated when that
structure is known, or omitted so the same representation can be refined
later as launch and loop parallelism are decided.
- acc.private_local takes that handle and yields the concrete storage
for the current execution context(for example the slice that corresponds
to this gang or worker).
[flang] Fix missed access group attribute when converting FIR to LLVM dialect. (#195376)
Apply group access attribute to memcpy when lowering fir.load/fir.store
of a box if an original FIR operation had it.
[asan] Change error to note when poison record is not found (#195669)
When `CheckPoisonRecords` fails to find a record, it's often due to the
history buffer being too small rather than a functional error in the
logic.
