[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
procdesc: add NOTE_PDSIGCHLD
The note type wakes up when there is something for pdwait(2) to report
on the process descriptor.

kern_thread: Fix i386 p_emuldata KBI assertion
On amd64 there was 4 bytes of padding between the 20-byte p_comm and
(for LP64) 8-byte p_sysent, so the addition of p_execblock just caused
that padding to be eaten up. However, on i386, there was no such
padding, and so the addition of p_execblock rippled through to
p_emuldata.

Revert "chflags: Add a new UF_DONTCACHE flag"
This reverts commit 74654ba3b1b3bcf6ba8870a54310accbb6adbf0b.
Apparently it breaks cross building from Linux for some
reason. I'll admit I didn't even know we supported cross
building from Linux.
[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.
fix "ifconfig vebX -tagged ifX"
it was wired up in the code to expect an extra argument, which isn't
needed or expected as it is meant to clear all the tags on the
interface.

[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.
