(Byte Code) VM loops over a set of bytes and executes them according to the set
of rules defined in the Ethereum yellow paper. When the BC VM is invoked it
invokes the JIT VM in a seperate goroutine and compiles the byte code in JIT
instructions.
The JIT VM, when invoked, loops around a set of pre-defined instructions until
it either runs of gas, causes an internel error, returns or stops. At a later
it either runs of gas, causes an internal error, returns or stops. At a later
stage the JIT VM will see some additional features that will cause sets of
instructions to be compiled down to segments. Segments are sets of instructions
that can be ran in one go saving precious time during execution.
