[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.

lang/clx: Update to 0.3.0
Drop the post-install workaround: upstream now installs clx_simd.h
itself. Add lib/libclx_lua.a, a new static library built from the
vendored Lua 5.5 sources.
security/zeek: Update to 8.0.10
