Add some overloaded functions that provide uniform debug dump
function names.  These names are:

  debug: the general debug dumper
  debug_verbose: for more details
  debug_raw: for the gory details
  debug_head: for the heads of declarations, e.g. function heads
  debug_body: for the bodies of declarations, e.g. function bodies

Not all types have the last four versions.

The debug functions come in two flavors, those that take pointers
to the type, and those that take references to the type.  The first
handles printing of '<nil>' for null pointers.  The second assumes
a valid reference, and prints the content.


Example uses are as follows:

  cp_token t, *p;
  debug (t);
  debug (p);

From the debugger, use

  call debug (t)


The functions sets implemented are:

debug (only)

    basic_block_def, const bitmap_head_def, cp_binding_level,
    cp_parser, cp_token, data_reference, die_struct, edge_def,
    gimple_statement_d, ira_allocno, ira_allocno_copy, live_range,
    lra_live_range, omega_pb_d, pt_solution, const rtx_def, sreal,
    tree_live_info_d, _var_map,

    vec<cp_token, va_gc>, vec<data_reference_p>, vec<ddr_p>,
    vec<rtx>, vec<tree, va_gc>,

debug and debug_raw

    simple_bitmap_def

debug and debug_verbose

    expr_def, struct loop, vinsn_def

debug, debug_raw, debug_verbose, debug_head, debug_body

    const tree_node


This patch is somewhat different from the original plan at
gcc.gnu.org/wiki/cxx-conversion/debugging-dumps.  The reason
is that gdb has an incomplete implementation of C++ call syntax;
requiring explicit specification of template arguments and explicit
specification of function arguments even when they have default
values.  So, the original plan would have required typing

  call dump <cp_token> (t, 0, 0, stderr)

which is undesireable.  Instead instead of templates, we overload
plain functions.  This adds a small burden of manually adding
the pointer version of dump for each type.  Instead of default
function arguments, we simply assume the default values.  Most of
the underlying dump functions did not use the options and indent
parameters anyway.  Several provide FILE* parameters, but we expect
debugging to use stderr anyway.  So, the explicit specification of
arguments was not as valuable as we thought initially.  Finally,
a change of name from dump to debug reflect the implicit output
to stderr.
