	* exppritn.c (print_subexp, dump_expression):  Add case for
	OP_BITSTRING.
	* expression.h (OP_BITSTRING):  New expression element type for
	packed bitstrings.
	* expression.h (EXP_ELEM_TO_BYTES, BYTES_TO_EXP_ELEM):  New
	macros to convert between number of expression elements and bytes
	to store that many elements.
	* i960-tdep.c (leafproc_return):  Use new macros to access
	minimal symbol name and address fields.
	* m88k-pinsn.c (sprint_address):  Use new macros to access
	minimal symbol name and address fields.
	* nindy-tdep.c (nindy_frame_chain_valid):  Use new macro to access
	minimal symbol address field.
	* parse.c (write_exp_elt, write_exp_string, prefixify_expression,
	parse_exp_1):  Use new EXP_ELEM_TO_BYTES macro.
	* parse.c (write_exp_string, length_of_subexp, prefixify_expression):
	Use new BYTES_TO_EXP_ELEM macro.
	* parse.c (write_exp_bitstring):  New function to write packed
	bitstrings into the expression element vector.
	* parse.c (length_of_subexp, prefixify_subexp):  Add case for
	OP_BITSTRING.
	* parser-defs.h (struct stoken):  Document that it is used for
	OP_BITSTRING as well as OP_STRING.
	* parser-defs.h (write_exp_bitstring):  Add prototype.
	**** start-sanitize-chill ****
	* ch-exp.y (BIT_STRING_LITERAL):  Change token type to sval.
	* ch-exp.y (NUM, PRED, SUCC, ABS, CARD, MAX, MIN, SIZE, UPPER,
	LOWER, LENGTH):  New tokens for keywords.
	* ch-exp.y (chill_value_built_in_routine_call, mode_argument,
	upper_lower_argument, length_argument, array_mode_name,
	string_mode_name, variant_structure_mode_name):  New non-terminals
	and productions.
	* ch-exp.y (literal):  Useful production for BIT_STRING_LITERAL.
	* ch-exp.y (match_bitstring_literal):  New lexer support function
	to recognize bitstring literals.
	* ch-exp.y (tokentab6):  New token table for 6 character keywords.
	* ch-exp.y (tokentab5):  Add LOWER, UPPER.
	* ch-exp.y (tokentab4):  Add PRED, SUCC, CARD, SIZE.
	* ch-exp.y (tokentab3):  Add NUM, ABS, MIN, MAX.
	* ch-exp.y (yylex):  Check tokentab6.
	* ch-exp.y (yylex):  Call match_bitstring_literal.
