[lldb] Format `atomic<shared_ptr>` on MSVC STL (#237631)
Continues #174218 and adds support for atomic shared and weak pointers.
The MSVC STL stores both shared and weak pointers as:
```cpp
template <class _Ty>
class _Atomic_ptr_base {
atomic<remove_extent_t<_Ty>*> _Ptr{nullptr};
mutable _Locked_pointer<_Ref_count_base> _Repptr;
};
```
Similar to #174218, I factored out the formatting of the summary.
Getting to the `_Ref_count_base` struct is a bit inconvenient for PDB,
because it doesn't reflect the type inside a field and template
parameters are unavailable.

[GlobalISel] Fixup commuted combine matching
Match the subtraction on either side of (A-C1)+C2. Check constants and
use counts through the matched operands.
Look through single-use copies when unmerging constants to avoid extra
AMDGPU materializations. Preserve shared constants and copies, physical
register copies, and constant-fold barriers.
Cover commuted subtraction and copied constants in MIR tests, and update
affected AMDGPU assembly checks.
[DirectX] Move class declarations to DirectX.h
This mirrors the other ~10 targets that have been fully ported to the
NewPM and avoids needing very small headers for ~3 line class
declarations.

[Driver][Darwin] Forward the -O option to the linker (#237432)
Pass the last -O option to the Darwin linker when the linker version is
at least 900. ld64 supports -O<level> starting with that version and
uses it to control link time optimizations such as deduplicating symbol
strings and to pick faster algorithms in unoptimized builds.

[MLIR][ROCDL] Note the deprecation of the <4 x i32> buffer ops (#231303)
While we don't have a way to flag a MLIR op as deprecated yet, go
ahead and add a note to the old `<4 x i32>` intriinsic ops that
they're actively deprecated.

wrote up this message.
net/igmpproxy: Fix igmpproxy_conf rc.d knob, document user and chroot
- The rc.d script documented igmpproxy_conf but read igmpproxy_config,
and required_files always pointed to the default path. Honor
igmpproxy_conf, keeping igmpproxy_config as a fallback so existing
setups do not break, and check the file actually in use.
- Add commented user and chroot examples to the sample configuration.
They allow igmpproxy to drop privileges once sysutils/mac_igmpproxy
is loaded.

sysutils/mac_igmpproxy: New port, MAC policy for net/igmpproxy
A MAC framework policy that grants the multicast routing privilege to
a single configurable UID, so net/igmpproxy can drop root and run as
the new igmpproxy user (UID/GID 422). The policy can be tuned or
disabled with the security.mac.igmpproxy.uid and
security.mac.igmpproxy.enabled sysctls.

net/dhcpdump: Update to 2.00 and switch to the active fork
The original dhcpdump 1.8 has not been maintained for many years. Move
to the dhcpdump-org fork, which Debian and Fedora already ship.
Changes since 1.8 include VLAN (802.1Q/802.1ad) support, reading from
pcap files, an option to dump the whole packet in hex, option 82/121/
249/93/94/116 decoding, updated IANA option names and several fixes for
out-of-bounds reads on crafted packets.
Add a TUI option, enabled by default, for the new interactive session
tracking interface (-t). It depends on devel/yascreen.

devel/yascreen: New port, curses replacement library
yascreen is a small curses replacement library for daemons and embedded
applications. It has no external dependencies, supports internal and
external event loops, can work over stdin/stdout or a socket (including
basic telnet sequences) and handles Unicode.
It is needed by the interactive TUI of net/dhcpdump 2.x.

emulators/open-vm-tools: Use fixed name and rcvar in vmware-kmod
vmware-kmod handles two kernel modules by setting name and rcvar from
$kernel_mod and calling run_rc_command twice. Tools that read rcvar
without running the script, such as service -e, see the unexpanded
variable and check the nonexistent $vmware_guest__enable, warning on
every host where the package is installed.
Give the script a fixed name (vmware_guest_kmod) and rcvar
(vmware_guest_kmod_enable), and have start and status loop over the
modules, each honoring its own knob. The script name and rc.conf
knobs are unchanged: vmware_guest_kmod_enable (default YES) still
supplies the defaults for vmware_guest_vmmemctl_enable and
vmware_guest_vmblock_enable, either of which can still be enabled on
its own, and rc.conf.d files for the per-module names are still read.

security/sudo: Put base system directories first in secure_path
The default sudoers file installed by the port has an active
secure_path line inherited from upstream's configure.ac, which lists
/usr/local/sbin and /usr/local/bin before the base system directories.
That is a Linux convention. On FreeBSD, LOCALBASE belongs to
ports/packages and the base system comes first everywhere else, so a
binary under /usr/local/bin could shadow a base utility when run
through sudo.
Set --with-secure-path-value so the default sudoers uses
/sbin:/bin:/usr/sbin:/usr/bin:${LOCALBASE}/sbin:${LOCALBASE}/bin.
Existing installations that edited /usr/local/etc/sudoers are not
affected.

security/sudo: Add LOGSRVD option and rc.d script for sudo_logsrvd
- Add a LOGSRVD option, enabled by default so current users see no
change, to build sudo_logsrvd and sudo_sendlog. When disabled the
server, its sample configuration, rc script and man pages are not
installed (--disable-log-server).
- Install an rc.d script for sudo_logsrvd. It is disabled by default,
enable it with sudo_logsrvd_enable=YES.
- Fix the SSL option description. It does not affect sudo itself, only
TLS for sudo_logsrvd and I/O log transfer.

mail/dma: Update to upstream master (f4e1d913)
The port pinned GH_TAGNAME to a commit that predates the v0.14 tag, so
the package lacked VERIFYCERT and SNI support in TLS. Pin the current
upstream master instead, which contains v0.14 plus following changes:
- LMTP: support relaying to an LMTP endpoint
- AUTH PLAIN support, with clearer syslog output when the server
offers no usable auth mechanism
- HELO fallback when the server rejects EHLO
- Accept "|" as separator between smarthost and password
- Terminate each local mbox message with an empty line (RFC 4155)
- Discard bounce queue items when handling a double bounce
- Cast ctype arguments to unsigned char
- Disambiguate two identical error messages (issue #139)
- Fix building bsd/ after "make obj"; dma.8 and SPDX updates

[lldb][test] Expect underlying types for typedefs with PDB in five tests (#238170)
`CodeView` has no type record for a typedef, and variables refer to the
underlying type directly, so with PDB debug info frame variable shows
unsigned int where DWARF shows `uint32_t`, `__int128` for `__int128_t`,
etc.
In these five tests the typedef name is incidental to what is tested, so
this patch expects the underlying type when the test runs with PDB, as
the STL data formatter tests already do, and enables PDB on them.

[lld-macho] Don't write chained fixups through misaligned pointers (#238485)
`DYLD_CHAINED_PTR_64` fixups only need to be 4-byte aligned, but later
patched their `next` fields, through pointers to
`dyld_chained_ptr_64_rebase` and `dyld_chained_ptr_64_bind`, which need
8-byte alignment. UBSan has flagged this since #234006 added a
4-byte-aligned fixup to chained-fixups-alignment.s.
Now we build them in locals and memcpy them in and out. arm64e fixups
have to be 8-byte aligned, so those writes are fine as they are. The
test now also has a bind and a `next` field at 4 mod 8, and checks that
the chain still decodes.
Fixes the sanitizer-x86_64-linux-fast failure after #234006:

Reapply "[SelectionDAG] Narrow (shr (sub A, B), 1) to AVGSUBFLOOR" (#238249) (#238408)
Needed to regenerate 2 tests to remove pzext.h.b.
Original message:
Add combineShiftToAVGSUB, which forms AVGSUBFLOORS/AVGSUBFLOORU on a
narrower type when both operands are known to be extended from it, so
the subtract can't overflow. This is similar to combineShiftToAVG.
The node is only formed if it is legal or custom on the narrow type or
the original type after type legalization. As long as type legalization
won't change the element type. This covers WidenVector, SplitVector and
ScalarizeVector. This can be relaxed in the future.
Remove the RISC-V P extension truncate combine for (P)ASUB(U) since this
is now handled by the generic combine.
[libc] Make ldexpf128/scalbnf128/scalblnf128 use emulated Float128 (#220295)
This makes the three exponent scaling functions ldexpf128, scalbnf128

[GlobalISel] Auto-commute combine patterns
Emit both operand orders for constrained commutative generic match
patterns, including each use of a PatFrag. Skip redundant permutations
and enforce MaxPermutations before allocating expanded alternatives.
Give each permutation its own operand expansions so operand indices
cannot leak between alternatives.
Keep commuted immediate patterns available with constant-to-RHS
canonicalization, and consolidate AMDGPU carry rules while preserving
zero-addend and RHS-first matching.
Make the integer and AMDGPU multiply/select helpers accept either operand
order.
Add emitter documentation and TableGen, MIR, and codegen regressions.
