c-decl.c (current_function_decl): Move to toplev.c.

	* c-decl.c (current_function_decl): Move to toplev.c.
	(init_decl_processing): Don't add current_function_decl as a ggc
	root here.
	* dbxout.c (dbxout_symbol): Change return type to int.
	(dbxout_symbol_location, dbxout_syms): Likewise.
	(dbxout_block): Don't emit LBRAC/RBRAC pairs for blocks without
	any locals. Use current_function_func_begin_label if set.
	* dbxout.h (dbxout_symbol, dbxout_syms): Change return type.
	* dwarf2out.c (dwarf2out_begin_prologue): Set
	current_function_func_begin_label.
	* final.c (final_start_function): Reset it.
	* toplev.c (current_function_decl): Define it here.
	(current_function_func_begin_label): New variable.
	(main): Add both as ggc roots.
	* tree.h (current_function_func_begin_label): Declare.
	* ch/decl.c (current_function_decl): Move to toplev.c.
	* cp/decl.c (current_function_decl): Move to toplev.c.
	* f/com.c (current_function_decl): Move to toplev.c.
	* java/decl.c (current_function_decl): Move to toplev.c.
