17329eea64 compiler: remove jumps to the next instruction 
In case there are no returns in the inlined function, jumps point to the
next instruction and can be omitted. This optimization can be extended
to handle other cases, here we just make sure that already existing code
stays the same.

ec3d1fae59 compiler: allow to find appropriate methods via selectors 
c.funcs contains function names using base types, while methods can be defined
on pointers and the value returned from c.getFuncNameFromSelector will have an
asterisk. We can't have the same name used for (*T) and (T) methods, so just
stripping the asterisk allows to get the right one.

6014dd720f compiler: don't push X onto the stack for inlined method calls 
Regular methods need this, because it'll be packed into parameters, but
inlined ones should deal with it in inlining code itself because method
receiver will be some local (aliased) variable anyway.

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.

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