Remove /etc/sudoers.d/zfs
The smartctl exception in /etc/sudoers.d/zfs doesn't cover devices
like NVMe or symlinked devices. Just get rid of it rather than
keep maintaining it.

[CIR] Implement Direct+canFlatten in CallConvLowering
CallConvLowering previously ignored the canFlatten flag on Direct
classifications: a Direct arg with a multi-field struct coerced type was
passed as a single struct argument rather than N scalar register arguments.
This is the register-passing pattern the x86-64 SysV ABI uses for structs
like struct { long a, b; }.
A new helper getFlattenedCoercedType centralizes the detection (Direct,
multi-field struct coercedType, canFlatten set). The three lowering sites
are updated: buildNewArgTypes pushes one wire type per field; insertArgCoercion
reassembles the coerced struct from N scalar block args then coerces to the
original type if the two differ; rewriteCallSite extracts each field via
cir.extract_member. The existing coerce-record-to-record-via-memory.cir
test gains can_flatten = false to opt into the single-arg path.
[CIR] Lower byval/byref args in CallConvLowering
ArgKind::Indirect arguments were hitting an errorNYI in
CIRABIRewriteContext. Add the lowering: in the callee the block argument
type changes to !cir.ptr<T>, a load is inserted at entry so the body sees
the original value type, and llvm.byval or llvm.byref is attached based on
ownership. At call sites, both byval and byref are lowered by allocating a
stack slot, copying the value in, and passing the pointer.
For byval, llvm.noalias and llvm.noundef are also added — llvm.noalias
because the call-site rewrite always produces a fresh alloca+store
(equivalent to -fpass-by-value-is-noalias), and llvm.noundef because the
copy is always fully defined. byref carries only llvm.byref and llvm.align
since it does not assert exclusive ownership.
[CIR] Lower sret returns in CallConvLowering
Functions that return an aggregate by value classify their return as
ArgKind::Indirect, but CallConvLowering reached an errorNYI for that
case, so the whole CallConv pass refused to lower any struct-returning
function.
rewriteFunctionDefinition now recognizes an Indirect return: the wire
return type becomes void, a hidden sret pointer is prepended as block
argument 0, and every cir.return is routed through that pointer. Rather
than storing the loaded return value through the sret pointer (a
byte-copy that breaks non-trivially-copyable types -- libstdc++'s SSO
std::string keeps a _M_p pointer into its own _M_local_buf, so a
byte-copy leaves the destination aliasing the source's dying stack
storage), insertSRetStores rewires the __retval alloca to the sret
pointer so construction flows directly into the caller's slot, matching
classic CodeGen's "construct into %agg.result" pattern. CIRGen emits one
cir.load __retval / cir.return pair per return statement, all reading the
single __retval alloca, so the alloca is rewired once and every return is

[CIR] Implement ArgKind::Expand in CallConvLowering
ArgKind::Expand classifies a struct argument for flattening: each field
becomes a separate scalar argument at the ABI level. Classic CodeGen
calls this "struct expansion" — used on targets like MIPS and some ARM
calling conventions.
CIRABIRewriteContext previously emitted errorNYI at both classification
sites. The replacement covers three call paths. In buildNewArgTypes,
the original struct type is replaced by one wire type per field. In
insertArgCoercion, the single struct block argument is replaced by N
scalar block arguments and an alloca+get_member+store+load sequence at
the entry block reassembles them for body uses; a running block-argument
index (rather than classIdx + sretOffset) correctly tracks the expanded
slot count when multiple Expand args or sret+Expand combinations appear.
The Ignore-drop loop gains a classToBlockArg pre-computation so that
Ignore args following Expand args are erased at the correct index. In
rewriteCallSite, cir.extract_member decomposes the struct operand into
its constituent fields, which become separate call arguments.

[WebAssembly] Fix crash combining complex numbers and multivalue (#200514)
This fixes a crash in Clang when the `experimental-mv` ABI is used on
WebAssembly targets in conjunction with complex numbers as arguments.
There's no strict definition for what the multivalue ABI is at this
time, so the main goal is to just not crash for now.

[libc++] Remove ios_base::__xindex_ from the ABI (#198994)
`__xindex_` is only ever used from the dylib from a single function. We
can simplify the code a bit by making the variable function-local and
avoiding exposing it to the ABI at all. This also fixes a TODO about
whether it's safe to use `atomic` with the GCC ABI: yes, since it's not
actually part of our ABI.

[HLSL][CBuffer][Matrix] Honor row_major/column_major keyword in cbuffer layout (#201671)
fixes #201668
A per-declaration `row_major`/`column_major` keyword on a cbuffer matrix
was being dropped when building the cbuffer layout, so the layout struct
and the buffer-layout copy fell back to the translation-unit
`-fmatrix-memory-layout=`
Needed to fix the desugar in two places:
* HLSLBufferLayoutBuilder::layOutMatrix took a `const ConstantMatrixType
*` and called ConvertTypeForMem(QualType(MT, 0)), discarding the sugar.
It now takes the sugared QualType.
* SemaHLSL's host-layout struct construction called
getUnqualifiedDesugaredType() on each field, erasing the orientation
attribute. A getHostLayoutFieldType() helper now keeps the sugared type
for constant matrices while desugaring everything else.
