 **Update 2** Tested with pre-release v0.70.  This code has immediate mode VM instruction for jump (`JMPI`), branch (`BRCI`), call (`JSRI`) and load (`LDAWI`, `LDRWI`, `LDABI`, `LDRBI`).  I have not done the same enhancement for the store instructions yet.  Benchmark time is reduced to 32 seconds from completion of loading bytecode until termination.  This is a pretty big speedup - 11.6 times as fast as the interpreter.
