Global variables that are not initialized may have their address set to zero.
Since multiple variables may have this address, we cannot apply the OSO relink address approach we normally use. However, the executable will have a matching symbol with a good address; this function attempts to find the correct address by looking into the executable's symbol table. If it succeeds, the expr_list is updated with the new address and the executable's symbol is returned.

Creates a DWARFExpressionList from an DW_AT_const_value.
This is either a block form, or a string, or a data form. For data forms, this returns an empty list, as we cannot initialize it properly without a SymbolFileType.
