Alexander Markov 6239c434fb [vm,cfe] Avoid elimination of 'x as Function' type casts 
Elimination of redundant type cast 'x as Function' where x is
a function type (such as 'void Function(int)') is not correct because
it changes semantics of a function call if such expression is
used as a receiver.

"Function" static type of receiver allows arbitrary function calls,
while known function type of the receiver means the call doesn't
need to check parameter types. Static type of receiver is currently
not stored in kernel AST but calculated from the receiver node,
so replacing 'x as Function' with 'x' changes static type of
the receiver from "Function" to function type.
