Implement support for Chill POWERSETs.
* ch-exp.y (operand_2): Implement 'Element IN PowerSet'.
* ch-typeprint.c (chill_type_print_base): Handle POWERSETs.
* ch-valprint.c (chill_val_print): Handle TYPE_CODE_SET.
* eval.c (evaluate_subexp): Implement BINOP_IN.
* expression.h (enum exp_opcode): Added BINOP_IN.
* gdbtypes.c (create_set_type), gdbtypes.h: New function.
* stabsread.c (read_type): If 'S', create a set type.
* valarith.c (value_bit_index, value_in), value.h: New functions,
for indexing in SETs.
