	* cgraphunit.c (analyze_functions): Set node->definition to
	false to signal symbol removal to debug_hooks->late_global_decl.
	* ipa.c (symbol_table::remove_unreachable_nodes): When not in
	WPA signal symbol removal to the debuginfo machinery.
	* dwarf2out.c (dwarf2out_late_global_decl): Instead of
	using early_finised to guard the we're called for symbol
	removal case look at the symtabs definition flag.
	(gen_variable_die): Remove redundant check.
