[libc++] Refactor `std::midpoint` tests and add constraint checks (#175388)
Refactor the `std::midpoint` tests and replace the verify test with
constraint checks.
[Offload] Fix llvm-gpu-loader after new argument (#198681)
Summary:
New argument added but was not included here. This gets out of sync just
because there's no reasonable way to build offload and this tool, it's
an unsolvable phase ordering problem so we just dlopen it.
Fix use-after-free in IOTransport::OnRead on client disconnect (#198548)
When an MCP client disconnects (EOF), `IOTransport::OnRead` called
`handler.OnClosed()` before resetting `m_read_handle`. The MCP server's
`OnClosed` handler erases the client from `m_instances`, destroying both
the transport (`this`) and the binder (`handler`). The subsequent
`m_read_handle.reset()` then accessed the destroyed transport's member,
causing a use-after-free (SIGSEGV).

[alpha.webkit.UncountedCallArgsChecker] Check arguments of CXXConstructExpr (#198454)
Check arguments of CXXConstructExpr like CallExpr.
This PR fixes a subtle bug in isCtorOfRetainPtrOrOSPtr that it was missing a check for OSObjectPtr, and it was getting an empty string for the name when getting called on a CXXConstructorDecl as well as similar bugs in isCtorOf* functions.
[clang][driver][darwin] Hold onto full triples in Darwin SDKPlatformInfo (#197791)
The architecture can be relevant when determining if an SDK supports a
particular triple. Record the full triples in SDKPlatformInfo instead of
all of the non-architecture triple components.

[flang] Improved FIR AA for acc.compute_region. (#198635)
We should actually treat the operand<->block-arg association
in `acc.compute_region` as a pass-through link, so that we can
accumulate the whole chain of addressing inside the compute region.
This is especially important for acc routines, where all `[hl]fir.declare`
operations are located inside `acc.compute_region`. The input operand,
in this case, is not a result of ACC entry/init operation.
The change in `FIROps.cpp` should be NFC, currently. I made it
just to align the pass-through handling with the AA change.
Even though I effectively replaced `ACC_DATA_ENTRY_OPS` with
`ACC_DATA_ENTRY_AND_INIT_OPS`, this change is not testable, because
boxed reductions are currently unsupported.
cap_net: do not allow new limits to drop keys from the old ones
If the old limit had family/hosts/sockaddr set, the new limit must
have them too. Before, a missing key in the new limit was treated as
"allow any", which let a caller silently extend their limits.

net-mgmt/thanos: Fix BUILD_DATE syntax to fix build
* Change the syntax of BUILD_DATE after switching to GO_LDFLAGS as
port was using double quotes but Uses/go.mk has single quotes where it
interpolates GO_LDFLAGS, which requires use of different syntax.
* Also switch date format of BUILD_DATE to classic ISO 8601.

membar_ops(3): Clarify language about membar_datadep_consumer.
I must have deleted a sentence about the temptation to pair it with
membar_producer in some earlier revision; let's write a new such
sentence.
