Add dwarf2_per_objfile member to DWARF batons
Various DWARF callbacks expect to be able to fetch the objfile and / or
dwarf2_per_objfile from the DWARF CU object. However, this won't be
possible once sharing is implemented.
Because these objects are related to full symbols (e.g., they are used
to implement location expressions), they can simply store the
dwarf2_per_objfile they need.
This patch adds a per_objfile member to the various "baton" structures
and arranges to set this value when constructing the baton.

(locexpr_describe_location, loclist_describe_location): Use new
member.
* dwarf2/read.c (read_call_site_scope)
(mark_common_block_symbol_computed, attr_to_dynamic_prop)
(dwarf2_const_value_attr, dwarf2_fetch_die_loc_sect_off)
(fill_in_loclist_baton, dwarf2_symbol_mark_computed,
