    Commit 920079b7935352c28385c17bc8c36256bebcd279 

This link https://github.com/llvm/llvm-project/pull/153252#discussion_r2275556144 details an instance where tablegen formatting through clang format follows the top version instead of the bottom.
```
def : Pat<(vec.vt(avgceilu(vec.vt V128:$lhs), (vec.vt V128:$rhs))), (inst $lhs,
 $rhs)>;
```

```
def : Pat<(vec.vt (avgceilu (vec.vt V128:$lhs), (vec.vt V128:$rhs))),
          (inst $lhs, $rhs)>;
```

Between `vec.vt` and `(avgceilu`, I would think the formatter would leave a whitespace
