cddd5e1f6d compiler: add a panic on internal lambda inconsistency
It's a bit better than behavior observer in #2281 (which is very cryptic).

db99368e96 compiler: optimize GAS cost of type conversion
CONVERT call base price is 8192. DUP, ISTYPE and JMPIF all cost 2. So we add
0.07% overhead in the worst case and save 99.93% otherwise.

At the same time, old code was just two bytes and new one is seven, but I
think it's tolerable considering how much GAS it can potentially save.

Fix #2250.

4d1e952be6 go.mod: update go-datastructures to 1.0.53
We're only using queue library and it didn't change in any way, but 1.0.53 has
proper go.mod, so it's still an improvement.

It at the same time pulls some new packages also like x/tools.

4249674ddc compiler: check for contract permissions
On many occassions we can determine at compile-time if contract config lacks
some properties it needs. This includes all native contract invocations
through stdlib, as both hashes and methods are known at compile-time
there.

6b3afe9131 compiler: inline all expression with no side-effects, fix #1881
This has the drawback of traversing expression each time the argument is
used. However this is not the case in our syscall/native wrappers.
The old behaviour can be restored by explicit local assignment.

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.

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
byte constant can be used both as integer and as an element
of byte-slice. Thus special case needs to be taken in
`append`.
