parse: warn about a 'case label' on empty statement
Commit 0d6bb7e1 ("handle more graciously labels with no statement",
2020-10-26) allowed a label to appear just before the closing brace
of a compound statement. This is not valid C (which would require
at least a null statement). Similarly, a case label is also not
allowed to appear just before a closing brace.
So, extend the solution of commit 0d6bb7e1 to issue a warning for
case labels and 'insert' a null statement.
Note that the next C standard (C23 ?) will allow even more freedom
in the placement of labels (see N2508 [1]) and make this placement
(along with others) legal C.
