    ## Description

When targeting `x86_64`, `i686`, `aarch64`, or `arm`, the following code crashes latest LLC with assertion error `i < NumUserOperands && "getOperand() out of range!"` in `llvm/include/llvm/IR/User.h:170: llvm::Value* llvm::User::getOperand(unsigned int) const` during `Interleaved Access Pass`

The code can compile successfully when targeting `wasm32`, `wasm64`, `riscv32`, `riscv64`.

## Minimal Reproduction

### Code

```ll
define void @f(ptr %p0, ptr %p1, ptr %p2) {
entry:
  %v0 = load <8 x i8>, ptr %p0
  %v1 = add <8 x i8> %v0, <i8 0, i8 1, i8 2, i8 3, i8 7, i8 7, i8 7, i8 7>
  %v2 = load <8 x i8>, ptr %p1
  %shuffled = shufflevector <8 x i8> %v2, <8 x i8> %v1, <4 x i32> <i32 0, i32 2, i32 4, i32 6>
  store <4 x i8> %shuffled, ptr %p2
  ret void
}
```

### Stack Trace
