[mlir][bufferization] Fix stale BufferOriginAnalysis in BufferDeallocationSimplification (#210105)

Fixes #205228

This change fixes a use-after-free bug in the
BufferDeallocationSimplification pipeline caused by the greedy pattern
rewriter deleting operation tracked by the BufferOriginAnalysis.
BufferViewFlowAnalysis (internally used by BufferOriginAnalysis) creates
the dependencies map once during initialization. In this specific case,
the folder removed the `memref.cast` ops making later uses a
use-after-free bug.

Below is the snippet of running the pass using
`-debug-only=greedy-rewriter`. It erases a `memref.cast` and crashes in
RemoveDeallocMemrefsContainedInRetained.

```
...
[greedy-rewriter:1] //===-------------------------------------------===//
[greedy-rewriter:1] Processing operation : 'memref.cast'(0x654d43d18670) {
[greedy-rewriter:1]   %4 = "memref.cast"(%3) : (memref<?x?xf32, 1>) -> memref<4x4xf32, 1>
[greedy-rewriter:1] 
[greedy-rewriter:1] } -> success : operation was folded
[greedy-rewriter:1] //===-------------------------------------------===//
[greedy-rewriter:1] ** Replace : 'memref.cast'(0x654d43d18670)
[greedy-rewriter:1] ** Modified: 'scf.yield'(0x654d43c97bb0)
[greedy-rewriter:1] ** Erase   : 'memref.cast'(0x654d43d18670)
...
[greedy-rewriter:1] Processing operation : 'bufferization.dealloc'(0x654d43cbd7d0) {
[greedy-rewriter:1]   %5 = "bufferization.dealloc"(%4#0, %1, %3) <{operandSegmentSizes = array<i32: 1, 1, 1>}> : (memref<f32, 1>, i1, memref<4x4xf32, 1>) -> i1
[greedy-rewriter:1] 
[greedy-rewriter:1] 
[greedy-rewriter:1]   * Pattern (anonymous namespace)::RemoveDeallocMemrefsContainedInRetained : 'bufferization.dealloc -> ()' {
```

The fix is to disable folding and split the canonicalization patterns to
run separately. This way, the patterns that rely on BufferOriginAnalysis
still work because folding was disabled and BufferOriginAnalysis never
invalidated. Then, the canonicalization patterns still benefit from
folding.

[X86][APX] Reuse EFLAGS across multi-predecessor blocks via NF in optimizeCompareInstr (#208184)

Extend optimizeCompareInstr to reuse EFLAGS produced in predecessor
blocks (including via NF variants) when a compare is redundant, covering
multi-predecessor, dominating, and cyclic CFGs. Share the NF-clobber
removal helper with FlagsCopyLowering, correctly handle swapped and
immediate-adjusted flag reuse, and simplify EFLAGS live-in marking.

Adds MIR tests exercising multi-predecessor reuse over cyclic and
dominating CFGs, including a multi-level idom walk.

[Github] symlink `llvm-tools` in libc container (#210561)

Missed thing in #210414. We need to symlink the LLVM tools that are
under `/usr/lib/llvm-23/bin/` to avoid errors like this because the LLVM
tools have a `-23` suffix when they're installed inside the container

[ADT] Add begin and end to EytzingerTableSpan and EytzingerTable (NFC) (#210478)

This patch adds iterator and const_iterator type aliases as well as
begin() and end() methods to EytzingerTableSpan and EytzingerTable.

I'm going to be using these as part of the SecNameTable in the
Eytzinger layout.
