974f5db6bc vm: add a TUCK implementation with tests
Also fix stack's InsertAt for the edge case of inserting into a position that
currently is empty (the first good TUCK test illustrates this).

eb224aeebe vm: add some checks for OVER and PICK, add OVER tests
These actually behaved correctly because of deferred sigsegv recover, but I
think it would be nice to print something more meaningful for users.

85831e3e92 vm: fix XTUCK implementation, add tests
The code that we have actually implements XTUCK and not TUCK. And it's a bit
broken, so fix it and add some tests. The most interesting one (that required
to touch stack code) is the one when we have 1 element on the stack and are
trying to tell XTUCK to push 2 elements deep.

b34a1b6c25 vm: harden tests against VM failures
Add a check for failed VM state, some of tests using logic values (like NZ
test) can succeed even with VM in FAULT state otherwise.

33c512032f vm: switch from Opcode to Instruction
Which matches the changes done in neo-storm and also make this codebase closer
to the `dev` branch (that also uses Instruction).
