  Log Message:
  -----------
  [clang] Make 'align-mismatch' warning work without an associated function declaration

This change fixes a crash where a NULL fd was used to emit a diagnostic.
Instead of crashing, just avoid printing the declaration name when there's no
associated function declaration.
