Haojian Wu d489b3807f [pseudo] Implement a guard to determine function declarator.
This eliminates some simple-declaration/function-definition false
parses.

- implement a function to determine whether a declarator ForestNode is a
  function declarator;
- extend the standard declarator to two guarded function-declarator and
  non-function-declarator nonterminals;

// The standard grammar allows an function-body to use any declarator, including
// a non-function declarator. This creates an ambiguity where a
// simple-declaration is misparsed as a function-definition.
