dwarf2.h (DW_OP_GNU_const_type, [...]): New.

	* dwarf2.h (DW_OP_GNU_const_type, DW_OP_GNU_regval_type,
	DW_OP_GNU_deref_type, DW_OP_GNU_convert, DW_OP_GNU_reinterpret): New.

	* dwarf2out.c (get_address_mode): New inline.
	(mem_loc_descriptor): Add MEM_MODE parameter, adjust recursive calls,
	if not dwarf_strict emit
	DW_OP_GNU_{{const,regval,deref}_type,convert,reinterpret} when
	desirable.  Handle FLOAT_EXTEND, FLOAT_TRUNCATE, FLOAT,
	UNSIGNED_FLOAT, FIX and UNSIGNED_FIX.  Just return NULL for
	FMA, STRICT_LOW_PART, CONST_VECTOR and CONST_FIXED.
	(dwarf2out_frame_debug_cfa_expression, reg_loc_descriptor,
	dw_loc_list_1, cst_pool_loc_descr, loc_list_from_tree): Adjust
	mem_loc_descriptor callers.
	(dwarf_stack_op_name, size_of_loc_descr, output_loc_operands,
	output_loc_operands_raw, hash_loc_operands, compare_loc_operands):
	Handle DW_OP_GNU_const_type, DW_OP_GNU_regval_type,
	DW_OP_GNU_deref_type, DW_OP_GNU_convert and DW_OP_GNU_reinterpret.
	(base_types): New variable.
	(get_base_type_offset, calc_base_type_die_sizes,
	base_type_for_mode, mark_base_types, base_type_cmp,
	move_marked_base_types): New functions.
	(calc_die_sizes): Assert that die_offset is 0 or equal to
	next_die_offset.
	(loc_descriptor): Only handle here lowpart SUBREGs of REG, for
	others defer to mem_loc_descriptor.  Adjust mem_loc_descriptor
	callers.  If not dwarf_strict, call mem_loc_descriptor even for
	non-MODE_INT modes or MODE_INT modes larger than DWARF2_ADDR_SIZE.
	(gen_subprogram_die): Don't give up on call site parameters
	with non-integral or large integral modes.  Adjust
	mem_loc_descriptor callers.
	(prune_unused_types): Call prune_unused_types_mark on base_types
	vector entries.
	(resolve_addr): Call mark_base_types.
	(dwarf2out_finish): Call move_marked_base_types.
