Subject: [PATCH] gdbhooks.py: add printers for analyzer types (supernode and
 exploded_node)

Tested by hand; this leads to output like this:

(gdb) p m_enode_for_diag
$1 = <ana::exploded_node 0x4e389f0 (EN 6)>

(gdb) p m_enode_for_diag->get_supernode ()
$2 = <ana::supernode 0x4da9030 (SN 1)>

gcc/ChangeLog:
	* gdbhooks.py (class AnaSupernodePrinter): New.
	(class AnaExplodedNodePrinter): New.
	(build_pretty_printer): Register the above.
