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,

	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.

	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.

	vector entries.
