The scopes are mainly used for symbols corresponding to variables
and functions with this hiearchy:
* builtin
* global
* function
* block
But the function_scope is only used for labels and __func__ and
is meaningless outside a function.
So, mainly in preparation for some incoming changes, let
function_scope's parent be NULL instead of the builtin scope.
