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 It is obsolete now.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.
