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: Vim9: problem when importing autoloaded scripts
Solution: In `:def` handle storing to vim9 autoload export
(Ernie Rael)
Problem occurs when `import autoload ./.../autoload/...`. The autoload
in the specified path causes the use of an autoload_prefix which combines
with the `import autoload` to create trouble.
In `generate_store_var()` `case dest_script` use ISN_STOREEXPORT,
when needed, instead of ISN_STORES. When executing ISN_STOREEXPORT,
check for autoload_prefix.

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 ac709e2fc0db6d31abb7da96f743c40956b60c3a

Problem: POSIX function name in exarg struct causes issues
on OpenVMS
Solution: Rename getline member in exarg struct to ea_getline,
remove isinf() workaround for VMS
There are compilers that do not treat well POSIX functions - like
getline - usage in the structs.
Older VMS compilers could digest this... but the newer OpenVMS compilers
( like VSI C x86-64 X7.4-843 (GEM 50XB9) ) cannot deal with these
structs. This could be limited to getline() that is defined via
getdelim() and might not affect all POSIX functions in general - but
avoiding POSIX function names usage in the structs is a "safe side"
practice without compromising the functionality or the code readability.
The previous OpenVMS X86 port used a workaround limiting the compiler
capabilities using __CRTL_VER_OVERRIDE=80400000
In order to make the OpenVMS port future proof, this pull request
proposes a possible solution.

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.
