dwarf2out.c (tree_add_const_value_attribute): Do not try rtl_for_decl_init during early phase. 

2016-10-13  Richard Biener  <rguenther@suse.de>

	* dwarf2out.c (tree_add_const_value_attribute): Do not try
	rtl_for_decl_init during early phase.
	(gen_variable_die): Do not create locations during early phase.
	(gen_label_die): Likewise.
	(decls_for_scope): Do not waste time handling BLOCK_NONLOCALIZED_VARs
	twice.
