[mlir][tosa] Move MUL shift value check out of verifier (#234063)
Keep `MulOp::verify()` local to the operation by removing its constant
`shift` value check. The existing strict `tosa-validate` check covers
invalid shift values.
Move the floating-point shift regression test to `error_if_check.mlir`.

mail/rspamd: Update to 4.2.3
Bug fix release. ARC forwarders whose seal fails verification are no
longer trusted (a whitelisted d= with a broken seal used to produce
ARC_ALLOW_TRUSTED and could lower DMARC), HTML and URL parsing now
follows browser rules so content after comments, CDATA or SVG/MathML
is no longer hidden from the scan, and a milter session use-after-free
on connection close is fixed.
Incompatible changes: phishtank.rspamd.com is disabled by default, and
duplicate RBL queries are merged so a rule now scores once per matched
value (set merge_checks = false to keep the old behaviour).

[CycleInfo] Add -verify-cycle-info and verify<machine-cycles> (#233412)
Add a -verify-cycle-info flag, on by default with EXPENSIVE_CHECKS,
following the example of -verify-loop-info. When it is set,
CycleInfoWrapperPass and MachineCycleInfoWrapperPass verify themselves
in verifyAnalysis(), which the legacy pass manager calls after each pass
that preserves them. This gives automatic verification of cycle info
across the legacy codegen pipeline.
Also add verify<machine-cycles> for the new pass manager, analogous to
verify<cycles>.

bnxt_en: dcb: stop zeroing ETS and PFC config in bnxt_dcb_init()
bnxt_dcb_init() currently pushes all-zero ETS and PFC settings to
the firmware at every attach. This reserves bandwidth allocation
for RoCE traffic, which prevents L2 traffic from reaching line rate.
These settings should only be updated with valid values when the
RoCE driver is loaded. Therefore, we should stop programming them
during bnxt_dcb_init().

[alpha.webkit.UnretainedLocalVarsChecker] Treat a raw pointer collection of a fast enumeration as the origin of its element (#234682)
alpha.webkit.UnretainedLocalVarsChecker still reported the element
variable of an Objective-C fast enumeration when the collection was a
raw pointer local variable or parameter, as in "NSArray *array =
obj.array;" followed by "for (T *x in array)", even though the variable
itself isn't reported. This includes a nested fast enumeration whose
collection is the element of the enclosing one, and a range-based for
loop over an Objective-C collection, which is a fast enumeration as
well.
The collection of a fast enumeration is evaluated before the loop body
is entered and keeps its elements alive. A raw pointer local variable or
parameter holding the collection is checked on its own, so treat it as a
guardian of the element as long as the loop body doesn't mutate it.
Also treat passing the address of an Objective-C object pointer guardian
as a mutation of the guardian as done for other raw pointers.

if_bnxt: Fix interrupt storm on Thor2
An interrupt storm was observed on Thor2 because the Rx CQ consumer
index was always one less than it should be. Correct the Rx CQ
consumer index to fix the storm.

[SimplifyCFG] Use check-globals=smart for test
Instead of manually writing out check lines for the test. This makes the

[bazel][compiler-rt] Introduce source exporting for ASan, UBSan, and LSan (#234492)
This exports the source files, headers, textual sources, and compile
flags for building the AddressSanitizer, UndefinedBehaviorSanitizer, and
LeakSanitizer runtime libraries on demand or via Bazel.
Also exports ignore lists and the basics needed for syms files. The
groups are decomposed in a way that allows us to build equivalent
runtimes to how CMake works. This is the basis that Carbon is building
on to support on-demand sanitizer runtimes.

[bazel][libcxx][libcxxabi] Introduce basic sources and copts exporting for libcxx and libcxxabi (#234489)
This exports the source files directly so that they can be used to build
a libcxx runtime library on demand. It also differentiates between
normal sources and textual sources in necessary places.
It also exports `.in` template files along with the source and headers.
And lastly, it exports `copts` to use when building both libcxx and
libcxxabi.

[AArch64][GlobalISel] Run shift_immed_chain in the post-legalizer combiner (#234727)
The legalizer can create chains of shifts by constants that the
pre-legalizer combiner never sees. Adding `shift_immed_chain` to the
post-legalizer combiner merges them.

[bazel][compiler-rt] Add `libfuzzer` target to `compiler-rt` (#234482)
This lets Bazel users of LLVM to also use `libfuzzer` directly to build
fuzz tests, including the `main`-function it provides. This is a simple
and uncomplicated approach to leveraging `libfuzzer`, and seems useful
to include. Carbon has been using it for the last several years
successfully.
One tricky part is that we have to carefully manage the compiler flags
when compiling with Clang.

Report TrueSearch in usage statistics services
## Problem
TrueSearch has no "Start Automatically" flag and no row in the services table, so it never shows up in the `services` list of the usage statistics and there is no way to tell how many systems use it.
## Solution
Append a `truesearch` entry to `services`, with `enabled` coming from `truesearch.enabled`, the same check middleware uses to decide whether to start the daemon (licensed, and SMB Spotlight or WebShare search have shares to index).
