void B() {

parse identifier expressions properly. This allows us diagnose this:
...
typedef int X;
int A() {
return X;
}
int B() {

}
as:
/Users/sabre/test.c:5:10: error: unexpected type name 'X': expected expression
return X;
^
/Users/sabre/test.c:9:10: error: use of undeclared 'Y' value

Two fixes:
...
1. Allow argument list of a call to be empty.
2. Handle expressions in a statement context that start with an identifier.
These are nasty to handle due to the 'label:' production which requires
having two tokens of look-ahead, or by having tricky code (which we
choose to do).
