[Passes] Port -print-pipeline-passes to PassesOptions (#230220)
-print-pipeline-passes takes an optional value (=text or =tree). Add
FlagOrEnumField, an EnumField whose bare option assigns a given
enumerator and never consumes the next argument, as cl::ValueOptional
does. BoolField and OptionalBoolField use the same BareValue.
clang, flang, LTO, llc, and opt read the format through
PassBuilder::getPrintPipelinePasses() instead of the exported cl::opt.

pcib: Only apply ARI translation to a bridge's own secondary bus
ARI changes RID interpretation only for the device on a downstream
port's secondary bus. pcib_xlate_ari() applied that translation to
every config access through an ARI-enabled bridge, including cycles
forwarded to a subordinate bus.
A non-zero slot on a subordinate bus then panics an INVARIANTS kernel
and is misrouted otherwise. Translate only when the access targets
this bridge's secondary bus.

ktls CBC decrypt: Avoid creating zero length iovec entries
If an mbuf's length in the chain for an encrypted TLS record exactly
matches the remaining length of header bytes to skip, skip the mbuf
entirely rather than adding a zero-length iovec entry.

route/fib_algo: Respect immediate_sync in fd_ref_nhop
Now fd_ref_nhop() returns zero for cross family routes,

[AMDGPU] Insert MFMA anti-hints in GCNPreRAOptimizations (#218075)
This PR adds rule-based anti-hints in the GCNPreRAOptimizations phase so
that
the register allocator prefers registers that avoid hazard nops.
Instructions
are classified into different classes and hazard windows are computed
from the
waitstate info. The rules are built to describe the hazardous situations
and
their hazard windows. Added an AntiHintEngine that uses these rules to
insert
anti-hint relations between vregs, which the register allocator later
uses to
prefer allocations that avoid the corresponding hazardous physical
registers.

Reject AFFINITY strides and nested vector subscripts
OpenMP allows a stride expression in an array section only where a clause
explicitly permits one, and AFFINITY does not. Semantics accepted positive
strides and lowering only reported a non-fatal error, so compilation
succeeded or crashed on the bounds. Report a stride in the last part
reference of an AFFINITY locator as a semantic error, including an explicit
unit stride. DEPEND and REDUCTION fall under the same rule but currently
accept strides; tightening them is left to a separate change.
The vector-subscript TODO for AFFINITY only checked the last part
reference, so a(v)%field(1) reached an assertion. Check every part
reference instead.
[cmake] Limit `/Zc:dllexportInlines-` flag to C/C++ (#227791)
This adjusts the way the `/Zc:dllexportInlines-` flag is passed so it
only takes effect for C and C++ targets built with clang-cl. These
changes are needed to prevent downstream consumers like Swift from
breaking due to being passed the flag.
The effort to build LLVM as a dylib is tracked in #109483.
[clangd] Clear LLVM_LINK_COMPONENTS for test plugin modules (#230359)
clang-tools-extra/clangd/CMakeLists.txt sets directory-scoped
LLVM_LINK_COMPONENTS (including Support), which is inherited by
clang-tools-extra/clangd/test/plugins/CMakeLists.txt.
When building ClangdFeatureModuleExample and
ClangdStandaloneTweakExample (added in #226995), llvm_add_library
statically links libLLVMSupport.a into the plugin shared libraries
unless LLVM_LINK_COMPONENTS is cleared before creating the targets.
Loading these plugins into clangd then triggers an ASan ODR violation on
llvm::vfs::FileSystem::ID because both clangd and the plugin module
contain their own copy of VirtualFileSystem.cpp.o.
Clear LLVM_LINK_COMPONENTS before calling llvm_add_library so the
plugins resolve LLVM symbols from the clangd executable at load time,
and remove the dead post-target LLVM_LINK_COMPONENTS block.
