[tsan] fit Go/s390x mapping under QEMU (#204503)
QEMU linux-user first tries guest_base=0. In that identity-mapped mode,
fixed guest mappings use the same host addresses. On an x86-64 host
with four-level page tables, the Go/s390x meta shadow starts at
144 TiB, beyond the 128 TiB userspace limit, and its mmap fails with
ENOMEM during TSan initialization.
Move the meta shadow down by 32 TiB to
[0x700000000000, 0x780000000000), restoring the 16 TiB gap after the
shadow and placing all Go/s390x TSan regions below 2^47. Correct the
mapping comment's shadow size and ratio.

[orc-rt] Sink Session::sendWrapperResult into Session.cpp. NFC. (#204956)
This function is never called inline (except by Session::wrapperReturn,
which is also in Session.cpp), so there's no need for it to be in the
header.
[SimplifyCFG] Avoid threading loop-header branches in convergent functions
SimplifyCFG can fold a conditional branch when the condition is known from
a predecessor. When the destination is a loop header in a convergent function,
this can change the dynamic convergence structure of the loop even though the
scalar CFG rewrite is otherwise valid.
Skip this fold for loop-header branches in convergent functions so convergent
control flow is preserved.
Fixes ROCM-26496.

[clang] Add clang-format-check-format instead to CLANG_TEST_DEPS (#204908)
Ensure that clang-format doesn't break the existing format of its own
source.

[AMDGPU][VOPD] Cache load reachability checks in VOPDpairing (#204854)
#201930 causes significant compilation time regression when building
ROCm mathlibs.
Major regressions are caused by repeated queries to `DAG->IsReachable`
to detect possible scalarisation of loads when fusing a pair of
VOPD-capable instructions.
This patch caches the set of reachable loads for every potentially
hazardous load instruction to avoid the need to invoke
`DAG->IsReachable` at all.
[SelectionDAG] Keep split vector atomic store value in a vector register (#201566)
When the value of an ATOMIC_STORE has a vector type whose legalization
action is split (e.g. <4 x half>/<4 x bfloat> on X86 without F16C),
SplitVecOp_ATOMIC_STORE bitcast the value straight to a scalar integer
spanning the memory width. For a split vector that bitcast is expanded
element by element, reassembling the value in GPRs (a long pextrw/shl/or
sequence) before the store.
Instead, keep the value in a vector register when a legal vector form
exists: reinterpret it as a same-shaped integer-element vector (an FP
element type may have no legal vector form, e.g. bfloat on SSE2, while
the integer-of-element-size form does), widen that to a legal vector,
and extract the low integer element of the memory width. This issues the
store directly from a vector register (a single MOVQ/MOVD on X86),
matching the widen-path codegen already produced on AVX targets. Falls
back to the scalar bitcast when no suitable legal vector type exists.

Convert system.vendor to the typesafe port pattern
## Context
system.vendor was an old-style service with inline BaseModel args/results and @api_method-wrapped methods. All three methods (name, unvendor, is_vendored) are private with no over-the-wire surface and there is no datastore, so it fits the fully-private port pattern — a lean private shim delegating to plain, fully type-annotated module functions — rather than a Generic*/Pydantic conversion. The wire shapes (str | None, bool, None) are unchanged.
## Solution
- vendor.py is now a plain typed logic module (get_vendor, remove_vendor_file, is_vendored); get_vendor stays importable there for scripts/vendor_service.py. The lean VendorService shim in __init__.py keeps the try/except + logging orchestration and delegates to it, with Config private. unvendor keeps the etc.generate string call since that's CtxMethod dynamic dispatch.
- Registered VendorService on SystemServicesContainer in main.py so it resolves as self.s.system.vendor.
- Switched the six in-process callers (support x2, usage x2, nvmet.subsys, device_ netlink events) from string middleware.call to call2/call_sync2 against the typed method handle.
- Added the plugin to the mypy workflow list.
