Consider the following code snippet test.c:

int test(int x) {
  static int arr[10] = {0, 1, 0, 0};
  return arr[x];
}

When lowering from CIR to LLVM using bin/clang test.c -Xclang -fclangir -Xclang -emit-llvm -S -o - It produces:

clangir/mlir/lib/IR/BuiltinAttributes.cpp:1015: static mlir::DenseElementsAttr mlir::DenseElementsAttr::get(mlir::ShapedType, llvm::ArrayRef<llvm::APInt>): Assertion `hasSameElementsOrSplat(type, values)' failed.

I traced the bug back to Lowering/LoweringHelpers.cpp where we fill trailing zeros, and I believe this PR does it the right way. I have also added a very simple test for verification.

Consider the following code snippet `test.c`: 

```
int test(int x) {
  static int arr[10] = {0, 1, 0, 0};
  return arr[x];
}
```

When lowering from CIR to LLVM using `bin/clang test.c -Xclang -fclangir
-Xclang -emit-llvm -S -o -` It produces:
```
