Changeset 4872dbdea907 replaced Address by Addr, but did not make changes to print statements. So the addresses which were being printed in hex earlier along with their line address, were now being printed in decimals. This patch adds a function printAddress(Addr) that can be used to print the address in hex along with the lines address. This function has been put to use in some of the places. At other places, change has been made to print just the address in hex.
