* dwarf2loc.c (struct piece_closure): Remove ARCH member, 

add ADDR_SIZE member.
	(allocate_piece_closure): Update.
	(copy_pieced_value_closure): Likewise.
	(dwarf2_evaluate_loc_desc): Likewise.
	(read_pieced_value): Use DWARF address size instead of
	GDB's gdbarch_addr_bit as size of values on the DWARF stack.
