This is to avoid polluting fuzzer seeds with the --ignition flag
until we figure out something better.

This change adds AbstractCode, which can be either Code or
BytecodeArray, and adds methods to calculate source position based
on that. Also cleans up to use code offsets instead of raw PC
where possible, and consistently uses the offset from instruction
start (as opposed to code object start).
