This is extremely expensive, so I don't think it's a good approach.
You can probably call cooked_index::lookup to see if an address is
covered:
/* Look up ADDR in the address map, and return either the
corresponding CU, or nullptr if the address could not be
found. */
dwarf2_per_cu *lookup (unrelocated_addr addr) override;
