(get_value): Always use get_default_value on uninitialized operands. (set_value_varying, surely_varying_stmt_p): New functions. (set_lattice_value): Do not pass argument to get_value. Do not handle UNKNOWN_VAL. (likely_value): Follow the semantics described in the comment. (ccp_initialize): Use surely_varying_stmt_p. Do not mark phi nodes DONT_SIMULATE_AGAIN. (ccp_fold): Do not pass argument to get_value. (fold_const_aggregate_ref, visit_assignment): Ditto.
