TRY can have an offset != 0 and still it can't have both parameters set to
zero.

stackitem: don't copy existing slices for TryBytes
...
Most often we only need to read them and it doesn't require copying. Make an
explicit copy (and copy only things we need!) where needed.
After the recent neo-vm tests update our vm package testing time jumped to
~12s, with this change it's now more like ~8s.

stackitem: add NewPointerWithHash() to save on hash calculations
...
Inspired by neo-project/neo-vm#352 . We can't directly compare slices, so we're
better optimize things we already have. At the same time this code would
behave a bit different if A is to call B and then B is call A and then some
pointer from the first A invocation is to be compared with a pointer from the
second A invocation. Not sure it really matters.

vm: fix debugger and add tests
...
1. `Run()` must be able to continue execution after a breakpoint.
2. VM must stop right before the breakpoint, not after.
3. Initial vm state is NONE, not HALT.

vm: check return value on context unload
...
When calling external contracts we expect exactly 1 value to be on
stack. For methods returning nothing, `Null` value is pushed, otherwise
it is an error.`

It's not needed any more with Go 1.13 as we have wrapping/unwrapping in base

Implement 3 new instructions: TRY,ENDTRY,ENDFINALLY.
1. TRY marks the start of the block where exceptions are catched.
It has 2 arguments which are relative offsets of exception handler
and the end of the whole try/catch construction.
2. ENDTRY denotes either end of try or catch block.
3. ENDFINALLY denotes end of finally block which is executed
irregardless of whether an exception has occured.
