gcc/ChangeLog:
    PR jit/63854
    * tree-pretty-print.c: Eliminate include of <new>.
    (buffer): Convert this variable from a pretty_printer to a
    pretty_printer *.
    (initialized): Eliminate this variable in favor of the NULL-ness
    of "buffer".
    (print_generic_decl): Update for "buffer" becoming a pointer.
    (print_generic_stmt): Likewise.
    (print_generic_stmt_indented): Likewise.
    (print_generic_expr): Likewise.
    (maybe_init_pretty_print): Likewise, allocating "buffer" on the
    heap and using its non-NULL-ness to ensure idempotency.
