tree.def (REALPART_EXPR, [...]): Change class to 'r'.

        * tree.def (REALPART_EXPR, IMAGPART_EXPR): Change class to 'r'.
        * fold-const.c (operand_equal_p <case 'r'>): Add REALPART_EXPR,
        IMAGPART_EXPR.
        * tree-dump.c (dequeue_and_dump): Handle REALPART_EXPR and
        IMAGPART_EXPR explicitly.
        * tree-inline.c (estimate_num_insns_1): Don't handle REALPART_EXPR
        and IMAGPART_EXPR specially.
        * tree.c (build1_stat): Copy TREE_THIS_VOLATILE into class 'r'.
