  Log Message:
  -----------
  [C] Disallow declarations where a statement is required (#92908)

This fixes a regression introduced in
8bd06d5b65845e5e01dd899a2deb773580460b89 where Clang began to accept a
declaration where a statement is required. e.g.,
```
if (1)
  int x; // Previously accepted, now properly rejected
```

Fixes #92775
