	* dwarf2read.c: Include "c-lang.h" and "valprint.h".
	(struct dwarf2_per_objfile) <reading_partial_symbols>: New field.
	(struct partial_die_info) <has_template_arguments>: New field.
	<num_attrs>: Change type to unsigned char.
	<building_fullname>: New field.
	(dwarf2_build_psymtabs_hard): Set reading_partial_symbols.  Only
	allocate a CU if we don't have one already.  Add a cleanup for the
	CU.
	(partial_die_full_name): Handle template arguments not in
	DW_AT_name.
	(dwarf2_psymtab_to_symtab): Clear reading_partial_symbols.
	(load_full_comp_unit): Only allocate a CU if we don't have one
	already.
	(do_ui_file_peek_last): New.
	(dwarf2_compute_name): Handle template parameters not in
	DW_AT_name.
	(read_comp_unit): Read and free abbrevs if not read yet.
	(load_partial_dies): Handle template arguments not in DW_AT_name.
	(find_partial_die): If we have a CU, but no a partial dies yet,
	also read in the CU.
	(dwarf2_const_value_attr): New, abstracted out from
	dwarf2_const_value.
	(dwarf2_const_value, dwarf2_const_value_data): Adjust to use
	dwarf2_const_value_attr.
	(determine_prefix): Detect and break loops created by RCVT's debug
	info.
	(maybe_queue_comp_unit): Bail out early if reading partial
	symbols.
	(follow_die_offset): Load full CU if we have no dies.
	* dwarf2loc.c (dwarf2_evaluate_loc_desc): Make public.
	* dwarf2loc.h (dwarf2_evaluate_loc_desc): Declare.
