	* dwarf2out.c (reg_save): For DW_CFA_expression put regnum
	into first operand and location into second.
	(dw_cfi_oprnd1_desc): Return dw_cfi_oprnd_reg_num instead of
	dw_cfi_oprnd_loc for DW_CFA_expression.
	(dw_cfi_oprnd2_desc): Return dw_cfi_oprnd_loc for DW_CFA_expression.
	(output_cfa_loc, output_cfa_loc_raw): For DW_CFA_expression
	assume first argument is regnum and second argument is location.
