Determines the addresses where both programs have initialized memory.
@param addrs the addresses to intersect with the initialized addresses
in common between the two programs.
The addresses in this address set should be derived from program1.
@return the addresses from the indicated address set that are initialized and in common.
The addresses in the returned address set are derived from program1.
