Auto creation of switch case does not work for anonymous enums

The quick fix for auto creation of switch case does not work for anonymous enums.

If we define a variable whose type is an anonymous enum, the quickfix cannot be triggered. For exemple, it does not work in this code:

  enum { A, B, C } toto;
  switch(toto) {
  }

The same thing happens if the enum is not anonymous, but the variable is defined in the same statement:

  enum XXX { A2, B2, C2 } toto2;
