The rationale in EIP-6[1] for changing names to `selfDestruct` applies to code as much as it does to specs. Also, Ethereum uses the new names consistently, so it's useful for our code to match the terms used in later EIP specs and testsuite entries. This change is straightforward, and is a prerequisite for patches to come that do things with the `selfDestruct` fields.
