Preventing NullStmts from being added into ForCtrl ended up being a larger rework as some timing issues caused problems. However, the NullStmts are mostly gone now along with the extra hosting they caused.

[de62360d]	16	// This grammar is based on the ANSI99/11 C grammar, specifically parts of EXPRESSION and STATEMENTS, and on the C
	17	// grammar by James A. Roskind, specifically parts of DECLARATIONS and EXTERNAL DEFINITIONS. While parts have been
	18	// copied, important changes have been made in all sections; these changes are sufficient to constitute a new grammar.
	19	// In particular, this grammar attempts to be more syntactically precise, i.e., it parses less incorrect language syntax
	20	// that must be subsequently rejected by semantic checks. Nevertheless, there are still several semantic checks
	21	// required and many are noted in the grammar. Finally, the grammar is extended with GCC and CFA language extensions.

	24	// the grammar.
[c11e31c]	25
	26	// The root language for this grammar is ANSI99/11 C. All of ANSI99/11 is parsed, except for:
	27	//
[9380add]	28	// designation with '=' (use ':' instead)
[c11e31c]	29	//
[9380add]	30	// This incompatibility is discussed in detail before the "designation" grammar rule. Most of the syntactic extensions
	31	// from ANSI90 to ANSI11 C are marked with the comment "C99/C11".
[f9c3100]	32
[e16eb460]	33	// This grammar also has two levels of extensions. The first extensions cover most of the GCC C extensions. All of the
[9380add]	34	// syntactic extensions for GCC C are marked with the comment "GCC". The second extensions are for Cforall (CFA), which
	35	// fixes several of C's outstanding problems and extends C with many modern language concepts. All of the syntactic
	36	// extensions for CFA C are marked with the comment "CFA".

[c11e31c]	580	//

[de62360d]	3987	// This pattern parses a new-style declaration of an abstract variable or function prototype, i.e., there is no
	3988	// identifier to which the type applies, e.g.:
[c11e31c]	3989	//
[b87a5ed]	3990	// [int] f( int ); // abstract variable parameter; no parameter name specified
	3991	// [int] f( [int] (int) ); // abstract function-prototype parameter; no parameter name specified
[c11e31c]	3992	//
	3993	// These rules need LR(3):
	3994	//
[c0aa336]	3995	// cfa_abstract_tuple identifier_or_type_name
[40de461]	3996	// '[' cfa_parameter_list ']' identifier_or_type_name '(' cfa_parameter_ellipsis_list_opt ')'
[c11e31c]	3997	//
	3998	// since a function return type can be syntactically identical to a tuple type:
	3999	//
[b87a5ed]	4000	// [int, int] t;
	4001	// [int, int] f( int );
[c11e31c]	4002	//
[2871210]	4003	// Therefore, it is necessary to look at the token after identifier_or_type_name to know when to reduce
[c0aa336]	4004	// cfa_abstract_tuple. To make this LR(1), several rules have to be flattened (lengthened) to allow the necessary
	4005	// lookahead. To accomplish this, cfa_abstract_declarator has an entry point without tuple, and tuple declarations are
	4006	// duplicated when appearing with cfa_function_specifier.
