How would you parse if (x) if (y); else z; ?
The general rule is that shift takes precedence over reduce,
so      if x ++ y;  ==>  if (x ++) y;

I am not saying allowing "if expr" is good language design (is the concept
relevant in a discussion about C?), just what I would expect if it were
allowed.
