Add function_type_arguments field in closure instances.
Lots of other smaller changes, also related to generic function semantics.
This is still work in progress, with a change of direction in the design:
The type argument vector of a generic function will be prepended with the type
arguments of enclosing generic functions. The re-allocation and concatenation
will be done in nested generic function's prolog. This will greatly simplify
instantiation of types at run time without having to search the context for
parent function's type arguments. However, a closure instance now requires an
additional field. On the other hand, type parameters do not require a
parent_level field anymore.

They were used as the class of closure instances and as the type class of
function types.
All closure instances now have class _Closure and function types are represented
by a new class FunctionType extending AbstractType.
Fix issue 24567 and add regression test.

By inserting the necessary checks for null inside the callee
at the AST level, the code generation of == operations can be
greatly simplified.
This is a performance-neutral change and a step for allowing
generic inlining of arbitrary == methods. So far we could only
inline them for a common set of types in the flow graph
optimizer.
