[CostModel] Handle all cost kinds in getCmpSelInstrCost (#148233)
Currently we always produce a cost of 1 for all CostKinds that are not
RecipThroughput, which can underestimate the cost if the type has a
higher legalization cost (like larger vectors). This relaxes it to cover
all cost kinds.
[C++] Fix a failed assertion with nullability checking (#148881)
This fixes a failed assertion with an operator call expression which
comes from a macro expansion when performing analysis for nullability
attributes.
Fixes #138371
[AtomicExpand] Add bitcasts when expanding load atomic vector
AtomicExpand fails for aligned `load atomic <n x T>` because it
does not find a compatible library call. This change adds appropriate
bitcasts so that the call can be lowered. It also adds support for
128 bit lowering in tablegen to support SSE/AVX.
[X86] Cast atomic vectors in IR to support floats
This commit casts floats to ints in an atomic load during AtomicExpand to support
floating point types. It also is required to support 128 bit vectors in SSE/AVX.
[clang] Fix pointer comparisons between pointers to constexpr-unknown (#147663)
A constexpr-unknown reference can be equal to an arbitrary value, except
values allocated during constant evaluation. Fix the handling.
The standard is unclear exactly which pointer comparisons count as
"unknown" in this context; for example, in some cases we could use
alignment to prove two constexpr-unknown references are not equal. I
decided to ignore all the cases involving variables not allocated during
constant evaluation.
While looking at this, I also spotted that there might be issues with
lifetimes, but I didn't try to address it.
CI: Add CentOS Stream 9/10 to the FULL_OS runner list
Testing on CentOS Stream provides several months advance notice of
changes coming to the RHEL kernel. This should help OpenZFS be
proactive instead of reactive to new RHEL minor versions.

[SelectionDAG] Widen <2 x T> vector types for atomic load
Vector types of 2 elements must be widened. This change does this
for vector types of atomic load in SelectionDAG
so that it can translate aligned vectors of >1 size.
[X86] Manage atomic load of fp -> int promotion in DAG
When lowering atomic <1 x T> vector types with floats, selection can fail since
this pattern is unsupported. To support this, floats can be casted to
an integer type of the same size.
[SelectionDAG] Legalize <1 x T> vector types for atomic load
`load atomic <1 x T>` is not valid. This change legalizes
vector types of atomic load via scalarization in SelectionDAG
so that it can, for example, translate from `v1i32` to `i32`.
IR/Verifier: Allow vector type in atomic load and store
Vector types on atomics are assumed to be invalid by the verifier. However,
this type can be valid if it is lowered by codegen.
NAS-136683 / 25.10 / Make sure we don't present a CA cert as a valid option for different services (#16734)
This PR adds changes to make sure that we flag certs which are CAs and
secondly make sure that when we present choices for different services
we have, we don't show CA certs as valid in them. Lastly when we
validate certs to be used with a service, we are also making sure that
the cert in question is not a CA

[lldb] Fix race condition in Process::WaitForProcessToStop() (#144919)
This PR addresses a race condition encountered when using LLDB through
the Python scripting interface.
I'm relatively new to LLDB, so feedback is very welcome, especially if
there's a more appropriate way to address this issue.
### Bug Description
When running a script that repeatedly calls
`debugger.GetListener().WaitForEvent()` in a loop, and at some point
invokes `process.Kill()` from within that loop to terminate the session,
a race condition can occur if `process.Kill()` is called around the same
time a breakpoint is hit.
### Race Condition Details
The issue arises when the following sequence of events happens:

[LLDB] Add formatters for MSVC STL std::tuple (#148548)
Adds synthetic children for MSVC STL's
[`std::tuple`](https://github.com/microsoft/STL/blob/313964b78a8fd5a52e7965e13781f735bcce13c5/stl/inc/tuple).
A `tuple` is a chain of base classes:
```cpp
template <>
class tuple<> {};
template <class _This, class... _Rest>
class tuple<_This, _Rest...> : private tuple<_Rest...> {
_Tuple_val<_This> _Myfirst;
};
```
So the provider walks the base classes to the desired one.
The implementation makes it hard to detect if the empty tuple is from
this STL. Fortunately, libstdc++'s synthetic children provider works for
