[Support] Add std::string overload for llvm::sys::path::native (#193228)
This patch adds an overload of `llvm::sys::path::native` that returns a
`std::string` directly, making it more convenient to use when a
`std::string` is needed instead of modifying a `SmallVectorImpl<char>`
in place.
This is for

[lldb] Fix pexpect detection with LLDB_ENFORCE_STRICT_TEST_REQUIREMENTS (#193444)
Fixes ec8df555702d85511290742388d28016b69468de / #193437.
In which I tried to not require pexpect on Windows because key parts of
it do not work there
(https://pexpect.readthedocs.io/en/stable/overview.html#windows).
Which I did but made a mistake which removed pexpect from the list of
required modules for *all* platforms as a side effect.
`list(APPEND pexpect)` creates an empty list called foo
(https://cmake.org/cmake/help/latest/command/list.html#append), I meant
to append to the useful modules list.
With that fixed, we require pexpect everywhere apart from Windows.
GitHub CI is already installing pexpect on Linux
(see .ci/all_requirements.txt). All the Linux bots using

[X86] Recognise vectors with zeros in all upper elements to improve VMOVS*Z folding (#193263)
Currently the VMOVSHZ (etc.) patterns are mainly limited to merging with
X86vzmovl patterns which explicitly demonstrate the upper elements
should be zero (and we can remove the X86vzmovl node).
This patch adds a X86vzelts PatLeaf to help match more general cases
where we can use the result of a passthrough node (in this case
X86vzload) is known to be zero in the upper elements via value tracking,
allowing us to fold to VMOVSHZ (but not remove the passthrough node).
Fixes #192034
[SelectionDAG] Preserve poison in IS_FPCLASS folds (#193246)
Handle poison explicitly in `IS_FPCLASS` so the fold preserves poison
semantics instead of turning the result into `false`.

[CIR] Fix __builtin_clz/__builtin_ctz poison_zero to respect target
CIR was hardcoding poisonZero=true for all clz/ctz builtins, ignoring
the target's isCLZForZeroUndef(). This caused incorrect UB on targets
like AArch64 where clz/ctz of zero is well-defined.
Also add support for __builtin_c[lt]zg fallback (2-arg) variants with
compare+select, and add NYI stubs for elementwise variants.
pmapmi: Define and use pmap_md_kernel_vaddr_{p,to_paddr} in pmap_extract.
Allow an architecture to provide a function that extracts the PA from the
VA that the kernel text/data/bss are mapped at. This allows pmap_extract
to work for kernel mappings that aren't PAGE_SIZE sized.
[libcxx][test] Skip cas_non_power_of_2.pass.cpp in Picolibc build (#191415)
Relates to #191388
This test is currently being run and failing to link, however this is
masked by the XFAIL for clang 21. It is also marked unsupported for 22,
for now.
I ran it with 23 and got this linker error:
```
| ld.lld: error: undefined symbol: __atomic_load
<...>
| ld.lld: error: undefined symbol: __atomic_compare_exchange
```
This happens because for 5 and 6 byte variables, we can't simply
generate code for the atomic, so we emit a library call, and the
picolibc build does not provide implementations of these functions.

du: Set BLOCKSIZE before running tests
Several testcases assume BLOCKSIZE=K, so set it at the top of the
script. This fixes an issue where the tests would sometimes fail
