Formatted printing for dump_* in the middle-end

This patch converts dump_print and dump_printf_loc from using
printf (and thus ATTRIBUTE_PRINTF) to using a new pretty-printer
based on pp_format, which supports formatting middle-end types.

In particular, the following codes are implemented (in addition
to the standard pretty_printer ones):

   %E: gimple *:
       Equivalent to: dump_gimple_expr (MSG_*, TDF_SLIM, stmt, 0)
   %G: gimple *:
       Equivalent to: dump_gimple_stmt (MSG_*, TDF_SLIM, stmt, 0)
   %T: tree:
       Equivalent to: dump_generic_expr (MSG_*, arg, TDF_SLIM).

Hence it becomes possible to convert e.g.:

  if (dump_enabled_p ())
    {
      dump_printf_loc (MSG_MISSED_OPTIMIZATION, vect_location,
                       "not vectorized: different sized vector "
                       "types in statement, ");
      dump_generic_expr (MSG_MISSED_OPTIMIZATION, TDF_SLIM, vectype);
      dump_printf (MSG_MISSED_OPTIMIZATION, " and ");
      dump_generic_expr (MSG_MISSED_OPTIMIZATION, TDF_SLIM, nunits_vectype);
      dump_printf (MSG_MISSED_OPTIMIZATION, "\n");
    }

into a one-liner:

  if (dump_enabled_p ())
    dump_printf_loc (MSG_MISSED_OPTIMIZATION, vect_location,
                     "not vectorized: different sized vector "
                     "types in statement, %T and %T\n",
                     vectype, nunits_vectype);

Unlike regular pretty-printers, this one captures optinfo_item
instances for the formatted chunks as appropriate, so that when
written out to a JSON optimization record, the relevant parts of
the message are labelled by type, and by source location (so that
e.g. %G is entirely equivalent to using dump_gimple_stmt).

dump_printf and dump_printf_loc become marked with
ATTRIBUTE_GCC_DUMP_PRINTF, which the patch also implements.
