Anton MedvedevandGitHub fee5690347 Refactor checker to use Nature (#665) 
This PR introduces a new concept inside Expr's type checker - Nature.

It's an abstraction other reflect.Type which carries additional information about possible type, methods and builtin function.

I was able to find and fix a few bugs in type checker and optimizer. Implementation of nature concept has proven itself. As well nature will allow to bring more feature for type checker in future.

Why Nature? I was looking for a name to replace Type. Type name already carries much information, as well can be confused with reflect.Type. Nature name should be understood as "nature of the node", same as "type of the node".

Augustin PeyrardandGitHub fe7f698b81 Fix Fetch and OpDeref (#467) 
* Fix OpDeref allowing to deref pointer of interfaces

Loop over `Ptr` and `Interface` kind and get `Elem`. Also return
directly the `nil` otherwise we might are returning the pointer nil
value and not the base nil.

* Fix deref interface in Fetch

We were only de-referencing pointers, but we can have pointer of
interface or interface obfuscating pointers...
So before trying to fetch anything, just deference fully the
variable.
