    Remove addr_size field from struct piece_closure
    
    The addr_size field in the piece_closure data structure is a relic from
    before introducing the typed DWARF stack.  It is obsolete now.  This patch
    removes it.
    
    gdb/ChangeLog:
    
    	* dwarf2loc.c (struct piece_closure) <addr_size>: Remove field.
    	(allocate_piece_closure): Drop addr_size parameter.
    	(dwarf2_evaluate_loc_desc_full): Adjust call to
    	allocate_piece_closure.
