I think it's useless, buggy and hides parsing errors for no good reason.

7b0c2781d2 vm: expand instruction list with commands from current VM spec
Current NEO documentation lists them:
https://docs.neo.org/docs/en-us/tooldev/advanced/neo_vm.html

CALL_* instructions were left out because of conflict with golint (but they're
removed in NEO 3.0 anyway, so wasting time on them makes no sense).

Update autogenerated instruction_string.go accordingly.

d4d1c79546 _pkg.dev: drop vm
This is a nice VM, it has an interesting stack items model, better separation
of elements from stack implementation, simpler stack implementation and a bit
nicer opcode implementation mechanism. At the same time it lacks so many
features and is so differing from our current VM (that is closely tied to the
compiler) that it makes its code very hard to reuse for master's VM
improvement.

Also, some differences are non-obvious to judge in terms of better or
worse. Stack item model seems to be more extensible, but at the same time we
know very well what kind of stack items we have and this doesn't change a
lot. Slice-based stack is simple but it's hard to say which one would perform
better for real-world smart contracts (it has different tradeoffs in
operations complexity).

Based on that, I'm dropping it. Some ideas will be reused during VM
refactoring, but no more than that. Refs. #307.

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.

e537dc9ee4 keys: improve publick key checks with a check against P
ANSI X9.62 says that if x or y coordinate are greater than or equal to
curve.Params().P, the conversion should return an error (see ANSI X9.62:2005
Section A.5.8 Step b, which invokes Section A.5.5, which does the check and
rejects when x or y are too big.

See https://github.com/golang/go/issues/20482 for more details.

2c3e92923f keys: simplify error handling for PublicKey() and associated
PublicKey() for PrivateKey now just can't fail and it makes no sense to return
an error from it. There is a lot of associated functionality for which this
also is true, so adjust it accordingly and simplify a lot of code.
