[MoveAutoInit] Moving an auto-init store into a block with a leading catchpad catches `-verify-memoryssa` asserts

```llvm
target triple = "x86_64-pc-windows-msvc"

declare void @dummy()
declare i32 @__CxxFrameHandler3(...)

define void @test() personality ptr @__CxxFrameHandler3 {
entry:
%p = alloca i32
store i32 0, ptr %p, !annotation !0
invoke void @dummy() to label %clean unwind label %catchbb

clean:
ret void

catchbb:
%cs = catchswitch within none [label %pad] unwind to caller

pad:
%c = catchpad within %cs [i32 0]
ret void
}

!0 = !{!"auto-init"}
```

```
$ opt -passes=move-auto-init -verify-memoryssa test.ll -disable-output
opt: llvm/lib/Analysis/MemorySSA.cpp:2096: void llvm::MemorySSA::verifyOrderingDominationAndDefUses(...): Assertion `&*ALI == *AAI && "Not the same accesses in the same order"' failed.
...
11 opt llvm::MoveAutoInitPass::run(llvm::Function&, llvm::AnalysisManager&)
```

Reproducer: https://godbolt.org/z/Kxqrdzq5b

Reproduce the failure with opt -passes=move-auto-init -verify-memoryssa using the provided test.ll, then inspect llvm/lib/Analysis/MemorySSA.cpp and the MoveAutoInitPass stack entry. Done means the reproducer completes with -verify-memoryssa enabled without the ordering assertion.
