Problem: Vim9: too recursive func calls when calling super-class method
with non-overriden super-call methods. (Aliaksei Budavei)
Solution: use interface method, when super is to be used (Ernie Rael)
When compiling "super.Func()" force class context to class that defines
function that is doing "super.Func()".
ISN_METHODCALL arg "cmf_is_super" for specific ufunc.

Problem: Vim9: cannot downcast an object (Ernie Rael)
Solution: Fix class downcasting issue (LemonBoy).
When casting an object from one class to another the target type may be
a subclass (downcast) or superclass (upcast) of the source one.
Upcasts require a runtime type check to be emitted.
Add a disassembly test.

Problem: is*() and to*() function may be unsafe
Solution: Add SAFE_* macros and start using those instead
(Keith Thompson)
Use SAFE_() macros for is*() and to*() functions
The standard is*() and to*() functions declared in <ctype.h> have
undefined behavior for negative arguments other than EOF. If plain char
is signed, passing an unchecked value from argv for from user input
to one of these functions has undefined behavior.
Solution: Add SAFE_*() macros that cast the argument to unsigned char.
Most implementations behave sanely for negative arguments, and most
character values in practice are non-negative, but it's still best
to avoid undefined behavior.
The change from #13347 has been omitted, as this has already been
separately fixed in commit ac709e2fc0

Problem: Vim9: builtin funcs may accept a non-value
Solution: Restrict builtin functions that accept `type`
This PR finishes off detection and prevention of using a type as a
value. It takes care of builtin functions. However there are some
builtin functions, that need to be able to handle types as well as
non-args: instanceof(), type(), typename(), string().
A "bit", FE_X, is added to funcentry_T; when set, the builtin function
can handle a type (class or type-alias) in addition to a value.
Noteworthy change: Discovered that in compile_call() the builtin add()
is compiled inline instead of calling the builtin. Had to add a check
there.

Problem: Vim9: No support for type aliases
Solution: Implement :type command
A type definition is giving a name to a type specification. This also known
type alias.
:type ListOfStrings = list<string>
The type alias can be used wherever a built-in type can be used. The type
alias name must start with an upper case character.

Problem: Vim9: restrict access to static vars and methods
Solution: Class members are accesible only from the class where they are
defined.
Based on the #13004 discussion, the following changes are made:
1) Static variables and methods are accessible only using the class
name and inside the class where they are defined.
2) Static variables and methods can be used without the class name in
the class where they are defined.
3) Static variables of a super class are not copied to the sub class.
4) A sub class can declare a class variable with the same name as the
super class.
5) When a method or member is found during compilation, use more
specific error messages.
This aligns the Vim9 class variable/method implementation with the Dart
implementation.
Also while at it, ignore duplicate class and object methods.
The access level of an object method can however be changed in a
subclass.
For the tests, use the new CheckSourceFailure() function instead of the
CheckScriptFailure() function in the tests.
