(fold_truthop): Treat a BIT_AND_EXPR with a constant of one as if it were
surrounded with an NE_EXPR.
(fold): Don't move operation into conditional if it is BIT_{AND,OR}_EXPR with

operations.
Don't make a SAVE_EXPR when moving things inside conditionals unless the value
would really have been used twice.
