  -----------
  [C] Do not diagnose unions with -Wdefault-const-init (#140725)

A default-initialized union with a const member is generally reasonable
in C and isn't necessarily incompatible with C++, so we now silence the
diagnostic in that case. However, we do still diagnose a const-
qualified, default-initialized union as that is incompatible with C++.
