[orc-rt] Add os_log logging backend (Darwin only) (#209081)

Implement the os_log backend, selected with ORC_RT_LOG_BACKEND=os_log.
With this backend selected, the ORC_RT_LOG macros expand at the call
site to os_log_with_type. Each ORC runtime log level maps to an
os_log_type_t (error -> ERROR, warning -> DEFAULT, info -> INFO, debug
-> DEBUG). The compile-time ORC_RT_LOG_LEVEL floor still applies, but
runtime filtering is left to the system (e.g. `log config`), so the
printf backend's ORC_RT_LOG and ORC_RT_LOG_OUTPUT have no effect.

Records go to the "org.llvm.orc-rt" subsystem with the category as the
os_log category. (Per-category handles are created on first use and
cached).

Add regression tests under test/regression/logging/os_log:
no-printf-output.test checks that the backend produces no console
output, and an opt-in delivery test (llvm-lit --param
run-os-log-tests=1) scrapes `log show` to confirm records reach the
expected subsystem and category.

[Flang] Fix for the spurious error for VOLATILE actual argument in implicit interface CALL (#192605)

Fixes #191343

Replaced the error with warning. Now it permits calling an external
procedure with implicit interface and passing a volatile argument. There
will be a warning that the procedure should have an explicit interface.

In addition to fixing the VOLATILE error, I updated the semantic check
for the ASYNCHRONOUS attribute. Both attributes were incorrectly
throwing a hard error when used as actual arguments in an implicit
interface call. According to the Fortran 2018 standard, an explicit
interface is only mandatory when the dummy argument has the VOLATILE or
ASYNCHRONOUS attribute. Since the standard doesn't restrict actual
arguments in this scenario, I downgraded both to emit a
-Wimplicit-interface-actual warning instead.

[SLP][Modularization][NFC] Extract type and constant helpers into SLPUtils (1/3) (#206881)

As we discussed on RFC:
https://discourse.llvm.org/t/modularizing-slpvectorizer-cpp/90922

This patch introduces the SLPVectorizer/ subdirectory and adds
SLPUtils.{h,cpp} under namespace llvm::slpvectorizer, then moves the
type and constant query helpers into it:
  - isConstant
  - isVectorLikeInstWithConstOps
  - isSplat
  - allConstant
  - allSameBlock
  - allSameType
  - allSameOpcode
  - getNumElements
  - getPartNumElems
  - getNumElems
  - getInsertExtractIndex
  - getExtractIndex

[BOLT] fix DIE traversal incorrect loop termination condition. (#208450)

The DIE traversal loop in partitionCUs() used an incorrect termination
condition, causing it to read past the end of the CU. Fix the loop to
stop at NextCUOffset so traversal no longer runs beyond the unit's
boundary.

Fixed [#208440](https://github.com/llvm/llvm-project/issues/208440).

[LLDB] Fix use-after-free destroying a Binder from its OnClosed handler (#209019)

transport::Binder::OnClosed() holds m_mutex (a recursive_mutex) while
invoking m_disconnect_handler. In the MCP server, that handler removes
the disconnected client, which owns the transport and therefore the
Binder itself. As a result, the Binder -- and its m_mutex -- are
destroyed while the scoped_lock in OnClosed still holds the lock.

This is a use-after-free everywhere, as the lock guard later unlocks
freed memory.

Move the disconnect handler out of the critical section and release the
lock before invoking it, so the Binder can be safely destroyed without
holding or destroying a locked mutex.

[LLDB][FreeBSD] Fill pgid and sid in ProcessInfo (#209009)

These two fields are required by HostTest.cpp. Although I don't see any
usecase, we add these two fields to prevent failure.

[SLP] Fix crash from repeated operand with mixed commutativity

A value used as both a commutable and non-commutable operand of the
same call got double-counted in dependency tracking, adding a
dependency scheduling never releases and tripping an assertion.

ReleaseNotes: add lld/ELF notes (#209066)

Summarize `git log origin/release/22.x..main` entries, excluding
cherry-picked notes `git rev-list main..origin/release/22.x -- lld/ELF`,
following the style of my previous release notes.

[ELF] Write the output to lld::outs() when -o is - (#209064)

When the output file is "-", write the image to lld::outs() (the
stdoutOS
argument of lld::elf::link()) instead of committing the
FileOutputBuffer,
which writes to the process's stdout. This lets lld used as a library
capture
the output in a raw_ostream without an open syscall.

This reimplements the stale #72061 and adds a unittest.

[Clang][Test] Fix -Wctad-maybe-unsupported in OperatorNewDeletePointersExtractorTest.cpp (#209012)

Fix warning: `'std::set' may not intend to support class template
argument deduction [-Wctad-maybe-unsupported]`, which is error under
-Werror.
std::set{*PtrId} does implicitly deduce to std::set<EntityId>, but it
is not explicit or user-defined CATD guide. Opt-in warning
-Wctad-maybe-unsupported flags it as maybe unsafe and unintended. The
warning is enabled at
https://github.com/llvm/llvm-project/blob/9083925dadb4/llvm/cmake/modules/HandleLLVMOptions.cmake#L977
Relates to #206600.

[ELF,test] Modernize --retain-symbols-file tests (#209062)

Switch to llvm-readelf, compact FileCheck directives, and
split-file-style naming. Prepares for a --retain-symbols-file behavior
change.

[SLP] Fix miscompile from truncating signed icmp constant

getActiveBits() ignores sign, so a positive constant needing the
narrower type's top bit was truncated to a negative value. Use
getSignificantBits() for signed comparisons.

[VPlan] Handle AtomicRMW/AtomicCmpXchg/Fence in outer loop creation. (#209031)

Teach VPInstruction::getNumOperandsForOpcode about AtomicRMW,
AtomicCmpXchg and Fence, so VPlan construction over an outer loop that
still contains these operations does not crash before later legality
rejects the loop.

Fixes crashes in the added tests.

[AArch64] Add an OPERAND_IMM_UINT5 operand type. (#209057)

This helps verify that certain operands are in the correct range, in
this case
0-31.

[VPlan] Add strided access test with disjoint or. (NFC) (#209051)

Currently this is missed by VPlan SCEV due to disjoint OR not being
handled.
