Warn or prevent users from sending to suicided contracts

During our estimate gas & prep params phase, could we also check if an address represents a contract that has died by suicide?

Requested by `@willwhite` on our slack.

Start by locating the estimate gas and prep params phase mentioned in the issue, then investigate how contract addresses and contract death are represented. Done means the flow reliably warns or prevents sending to a contract that has died by suicide, with the behavior covered by the relevant tests if they exist.
