libdw: Handle empty location expression for (indirect) DIE locations.

When dwarf_getlocation_implicit_pointer and dwarf_getlocation_attr
refer to a DIE that doesn't contain a DW_AT_location then don't generate
an error, but return an empty location expression to signal the actual
value pointed to is not available. This isn't invalid DWARF. Also make
sure that __libdw_intern_expression handles empty location expressions.
