Hi,
cgraph dumpnow segfaults as we have symbols without DECL_NAME set.  This patch makes
us to print node by asm name or as <unamed>  if everything fails.

Honza

	* symtab.c (symtab_node::asm_name): Do not call printable name directly.
	(symtab_node::name): Report name as unnamed if DECL_NAME is not set.
