VM CLI: set ip

[ixje]

I think it could be useful to have a command that allows for setting the instruction pointer. Right now you can load a nef, but run will always execute whatever function or code is at offset 0 (obviously). Having the ability to set the instruction pointer we could at least call some other functions (the offset can be grabbed from the manifest). Of course it's still limited to functions without arguments but that could be all you need sometimes.

@AnnaShaleva, IIUC run method works now even with 0.99.4? Arbitrary jumps can be useful anyway though.

Yes, it works.

Of course it's still limited to functions without arguments

Also, run method is able to parse arguments, e.g. run method arg1 arg2 .... After #2740 arguments parsing will work exactly as contract testinvokefunction works.

Arbitrary jumps can be useful anyway though.

I'll add some move or jmp command for this.
