middle-end/97855 - avoid recursing into pp_printf
When diagnostic messages use pretty-printer formats like %D or %E
the pp_printf invocation can end up in tree pretty-printers which
then have to avoid using pp_printf themselves since this function
is not re-entrant.
The following removes all pp_printf uses from tree-pretty-print.c
fixing the observed malformed diagnostics. It also poisons the
identifier so new uses are less likely to creep in.
