Removed the arbitrary precision VM in favour of the optimised JIT VM. This enables the new VM for all calls and creates and removed the need for the --jitvm and --forcejit flags. This fixes a minor issue when the jit is used in a multithreaded environment it would ignore the complitation status of the JIT and default to the byte-code VM. Instead it now waits for the compilation to finish and run the JIT if the execution was successful.
