Introduce an accumulator in the interpreter, and change instructions
This reduces the number of stores to the stack (for which we need a
write-barrier in the future) by keeping the last calculated value in the
accumulator register (which is a local variable).
In the future we might want to collapse certain common instruction
patterns into a super-sized instruction.
