switch some uses of ExpectAndConsume(tok::semi to use ExpectAndConsumeSemi.  This allows
us to improve this diagnostic (telling us to insert another ")":

t.c:2:19: error: expected ';' at end of declaration
  int x = 4+(5-12));
                  ^
                  ;
to:
t.c:2:19: error: extraneous ')' before ';'
  int x = 4+(5-12));
                  ^

...telling us to remove the ")".  This is PR12595.  There are more uses of ExpectAndConsumeSemi
that could be switched over, but I don't hit them on a daily basis :)
