[mlir] Fix integer overflow in ShapedType::getNumElements and `makeCanonicalStridedLayoutExpr` (#178395)
Add to `ShapedTypeInterface` a new `tryGetNumElements()` API which
returns `std::optional<int64_t>` - returns `std::nullopt` on overflow
instead of UB, using `llvm::checkedMul` for proper overflow detection.
`getNumElements()` now uses this new API to assert on overflow.
Also fix `AffineExpr` canonicalization to avoid crashing on overflow
using `llvm::checkedMul`.
Fixes #178362
Fixes #177816

[AArch64][Driver] Enable host supported features with march=native. (#177128)
Currently, march=native enables the base features implied by the host
system architecture, such as Armv8.2-A, Armv9-A, etc, rather than the
actual features supported by the host (e.g. crypto). This is suboptimal
as it generally leaves optional but supported features disabled.
This patch aligns the behaviour of march=native with mcpu=native by
using the latter's decoding logic to decode the former as well. This
means both options should enable a similar set of features. We also set
the target-cpu accordingly, so that march=native becomes a drop-in
replacement for mcpu=native.
[lldb][test] Add tests for formatting of command option descriptions (#178235)
These test the existing behaviour before I work on #177570.
I chose "breakpoint set" because it has options with ANSI underlines
in the description.
The tests cover no ANSI (use-colour off) and with ANSI (use-color on).
The latter is where we have problems right now.
nuageinit: support fetching configuration on multiple iface
On some environement a VM can be connected to multiple ifaces but only
one will respond to dhcp and able to fetch the metadata.
Launch the early dhclient on all available ifaces and as soon as one
dhcp has successfully configured an iface, proceed with fetching the
metadata.

[lldb] Fix memory monitor shutdown on Linux using eventfd (#178083)
The current linux implementation has a 1 second timeout when polling for
memory pressure. lldb-dap may take up to an extra 1 second to shutdown.
Use an event file descriptor to immediately stop the memory monitor
thread.
Fixes #150220
rpki-client: prepare p -> cert replacement in cert_buffer() and cert_read()
This wraps a few lines and pulls assignments out of if statements to avoid
overlong lines. The replacement will then become purely mechanical.

[AMDGPU] Change scale_src2 encoding from vgpr0 to literal 0 (#178404)
This changes the fix from #167777 to use the encoding for literal 0
instead of the encoding for vgpr0, to match new SP3 behaviour and for
consistency with all other unused VALU source operands since #175753.
[libc++][NFC] Remove _LIBCPP_FREESTANDING (#176907)
`_LIBCPP_FREESTANDING` isn't used and it is unclear what libc++'s
strategy is going to be for implementing freestanding at the moment.
Therefore, remove the macro.
[AMDGPU][GFX1250] Implement offset handling in s.buffer.load (#178389)
Divergent path of s.buffer.load must handle 32b offset extension
behaviour on GFX1250.
Tests in llvm.amdgcn.s.buffer.load.ll are rewritten to avoid using
export instructions not available on GFX1250.
[WebAssembly] Fix crash in ReplaceNodeResults for ANY_EXTEND_VECTOR_INREG (#178374)
Fixes a crash during type legalization by allowing
ISD::ANY_EXTEND_VECTOR_INREG to fall back to default expansion instead
of hitting llvm_unreachable.
Fixed: #177209
(cherry picked from commit 16d8d4b84edd257a81b243767d7b6bd62bbfb9fa)
[LifetimeSafety] Handle temporaries of non-trivial view types (#177878)
Fixes https://github.com/llvm/llvm-project/issues/177802
This enables the analysis to correctly track lifetimes through
non-trivial view types that require temporary binding due to having a
destructor.
This is fixed by handling `MaterializeTemporaryExpr` even for
lifetime-extended temporaries and fixing the flow of origins.
workflows/release-tasks: Add missing needs tag to release-lit job (#178224)
The job references variables from the validate-tag job, so it needs to
have it listed in the 'needs' tag. This is why this job failed for the
22.1.0-rc2 release.

sysutils/fluent-bit: fix problem with tail module
On FreeBSD, userland inotify functions do not accept IN_IGNORED and
IN_Q_OVERFLOW flags (they are only returned from system calls by
kernel), and if specified, invokes an error.
