[RISCV] Fix size of PseudoMERGE (#218171)

This can expand to two 4-byte instructions, so mark it as size 8.
Usually it will expand to just one 4-byte instruction.

This was found in #218170.

[NewPM] Port EHContGuardTargets to the new pass manager (#217843)

Adds a newPM pass for EHContGuardTargets (eh-cont-guard-targets).

- Extracts the pass's logic (which has no per-instance state) into a
shared runEHContGuardTargets free function, called by both the legacy
pass and the new pass manager pass.
- Renames the old pass with the "Legacy" suffix, and (matching the same
convention already applied to CFIInstrInserter) renames
createEHContGuardTargetsPass() to createEHContGuardTargetsLegacy() at
all three legacy call sites (X86, AArch64, ARM).
- Adds the new pass manager pass EHContGuardTargetsPass, using
RequiredPassInfoMixin: the legacy pass's runOnMachineFunction never
calls skipFunction, so it always runs unconditionally and should not be
skippable in the new PM either.
- Updates MachinePassRegistry.def and PassBuilder.
- Wires the pass into X86's newPM pipeline, replacing an existing TODO
inside the already-correct TT.isOSWindows() conditional in
X86CodeGenPassBuilder.cpp. AArch64 and ARM have no newPM

Fixes #217740.

Keep zero-mass exits in `solveIrreducibleMass`.

Although their mass is zero, these exits are later reused when building
enclosing irreducible SCCs... dropping them can change SCC membership

[clang] Trim large(-ish) includes from common headers (#216946)

Several widely included Clang headers pull in whole subsystems to name
types they only use through pointers, references, or declarations.
Because these headers sit underneath SourceManager.h, Sema.h, and
CompilerInstance.h, nearly every translation unit in Clang pays for
them, as well as many down-stream users of Clang.

Translation units across Clang and clang-tools-extra that were relying
on any of the removed transitive includes now include what they use.

Out-of-tree code that was relying on any of these transitive includes
needs the same treatment. The failure is an incomplete type or an
undeclared identifier at the point of use, and the fix is to include the
header that declares it; llvm/Support/VirtualFileSystem.h and AST/Attr.h
account for most of it, since Basic/FileManager.h and AST/GlobalDecl.h
are reached from so much of Clang.

Measured on a random 90 translation unit sample of clang's 1006 library

[DomTree] Make addChild/removeChild private, update NewGVN caller (#218164)

NewGVN's value numbering loop converges more quickly when blocks are
processed in a reverse post order. The code additionally ensures a
property the pass does not need (commit 6658cc9ead67 in 2016): in a
preorder of the dominator tree the instructions dominated by a block are
contiguous.

Use the default RPO and drop addChild/removeChild callers, so that the
two members can be made private. `opt -passes=newgvn` slightly
decreases.

[mlir][xegpu] Lower dynamic high-D nd load/store via base-pointer fold (#215711)

Reworks lowering of >2D (batched)
`xegpu.create_nd_tdesc`/`load_nd`/`store_nd`/ `prefetch_nd` (batched
GEMM, rank-4 flash-attention) to keep the full high-D memref as the
descriptor source and carry the leading (batch) offsets as a row offset
into a flattened 2D plane, instead of slicing a per-batch
`memref.subview` during blocking.
 
For example, the wg-level IR read a 4d vector out of a dynamic shaped
memref.
 ```mlir
    %0 = vector.transfer_read %source[%i, %j, %k, %l], %c0
{in_bounds = [true, true, true, true]} : memref<?x?x8x16xf32>,
vector<2x4x8x16xf32>
 ```
This lowers with no subview — the full memref is the descriptor source
and all four offsets stay on the load:

SelectionDAG: Fix widening of vector addrspacecast results (#217898)

WidenVecRes_ADDRSPACECAST unconditionally called GetWidenedVector on the
source operand, which asserts the operand is itself in the
widened-vector
map. When the source vector type does not require widening (e.g. a
<5 x ptr addrspace(3)> cast to <5 x ptr>, where the source is padded
rather than widened), this asserted or crashed. Handle the non-widened
source by padding it up to the widened element count instead.

[VPlan] Expand sequential/regular UMin SCEVs in VPSCEVExpander. (#209786)

Add support for expanding SequentialUMinExpr SCEV expressions in
VPSCEVExpander.

For regular UMin expressions, the expansion unconditionally expands &
executes all operands, while the semantics of sequential UMin only
require the first operand to be evaluated unconditionally.

For sequential UMin expressions, we need to make sure potentially
UB/poison generating operands must be accounted for. Matching IR SCEV
expander, make sure that divisors of UDiv are poison-free and non-zero
inside sequential UMin. Similarly, freeze all operands other than the
first, to avoid poison from propagating.

[InstSimplify] Simplify nonzero comparisons involving X urem Y via X u>= Y (#216072)

This teaches ValueTracking that `X` and `X urem Y` are non-equal when a
dominating condition implies `X u>= Y`.

It also handles cases where `X u>= Y` can be proven structurally, such
as when `X` is an `add nuw` of `A` and `Y`.

For a defined `urem`, let `R = X urem Y`. Then:

```text
R == X  <=>  X u< Y
R != X  <=>  X u>= Y
```

This allows InstSimplify's existing nonzero reasoning to simplify
comparisons equivalent to `(X - R) != 0`, including:

- `(X - R) u>= 1` and `(X - R) u< 1`

[clang-tidy] Fix false positives in readability-trailing-comma for designated initializers (#215934)

The problem is that we delete the necessary comma whenever we use
implicit initializer lists. How we solve this is that whenever we see an
implicit initializer list, we do not match ``InitListExpr`` nodes at
all, so that we will not delete the necessary comma. Why we chose this
path is detailed in Alternatives considered.

This produces a fix that breaks valid code (#214087) and one that never
converges (#214086).

<details>
<summary><b>Alternatives considered</b></summary>

### Why not repair the source ranges instead

The synthesized nodes also carry misleading locations - their range is a
snapshot of the designator that caused them to be created, so it need
not cover their own children. The anonymous-struct node in #214087

[clang-cl] Fix help string output for `/experimental:deterministic` option. NFC (#207083)

The `clang-cl -help` command show the help string for
`/experimental:deterministic` options with the default metavar name
value that should not be:

  /experimental:deterministic<value>

This patch fixes this output and omits the `<value>` part for the
option.

[DebugInfo][CodeView] Emit path prefix substitution for COFF object file name. (#205729)

The `S_OBJNAME` field value gets by bypassing `CGDebugInfo` and its path
prefix does not get remapped if requested `fdebug-prefix-map=` option as
the other pathes in the debug info. This patch fixes it and does
remapping for the object file path either.
