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 .

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.

This has the drawback of traversing expression each time the argument is

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.
