AddressesMap represents information about valid addresses used by debug information.
Valid addresses are those which points to live code sections. i.e. relocations for these addresses point into sections which would be/are placed into resulting binary.

This function checks whether variable has DWARF expression containing operation referencing live address(f.e.
DW_OP_addr, DW_OP_addrx...).
- Returns
- first is true if the expression has an operation referencing an address. second is the relocation adjustment value if the live address is referenced.
