7e9f8e03c2 compiler: add a test for inlined selector statements 
Selector here is either a struct field access or global package
variable/constant. While technically none of these require an additional

e754ca62db compiler: do not emit CONVERT for syscall results 
When we encounter type assertion CONVERT is emitted.
This isn't needed for SYSCALL (or opcode) results
because value already has needed type.
Problems can arise when result is converted to invalid type
but `neogointernal` package shouldn't be used directly anyway.

7577bbef22 compiler: copy locals slice during inline 
Consider function call `f(1, g(2, 3))` when
both `f` and `g` are inlined. If `f` contains some locals,
inlining `g` will replace them with it's another locals map,
because slices in Go reuse storage on `append`.
Thus scope needs to be copied.

b66b853285 compiler: drop stack after inline 
Some control-flow statements drop stack items, for example
`return` when it is used inside of `range` loop.
For inlined calls this `return` should drop only portion of stack
which belongs to inlined call.

fc3b840335 compiler: append bytes >0x80 properly 
NeoVM encoding for int(0x80) is []byte{0x80, 0x00} and

of byte-slice. Thus special case needs to be taken in
`append`.

compiler: save both VM and smartcontract types

cbf26f315c compiler: save both VM and smartcontract types 
VM types are used in debugger, while smartcontract ones are used in
manifest. We can't save only one of them, because conversion in either
side is lossy:
1. VM has `Array` and `Struct` but smartcontract only has `Array`.
2. Smartcontract has `Hash160` etc, which are all `ByteString` or
`Buffer` in VM.

And to spice things a bit more, return type in debugger can be `Void`,
which corresponds to no real stackitem type (as it must exist).

b7e86fa6a3 manifest: add Safe flag to method descriptor 
`interop.Contex.AddMethod` sets `Safe` flag for native
contracts. This allows not to forget to change manifest
when changing call flags.
Also fixed invalid `Safe` flags for `Notary` and `Designate` contracts.

```
"error encountered at instruction ** (NOT): runtime error: invalid memory address or nil pointer dereference"
