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  It is obsolete now.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.
