If we do not do this, the state-machine builder will not know the type
of the ACONST_NULL, defaulting to Object, leading to VerifyError.
Alternatively, we could use LVT to deduce the type, but getting types
from LVT is something I got rid of long time ago, and I have no desire
to return it back.
Generating CHECKCAST hints the state-machine builder the type of the
variable avoiding the issue of VerifyError. However, this CHECKCAST
replaces StrictBasicValue.NULL_VALUE with BasicValue in
OptimizationBasicInterpreter. To preserve optimization on not-spilling
known nulls, introduce BasicValues, which represent typed nulls and
create BasicInterpreter, which is aware of them. This way we have the
best of two worlds - we do not spill known nulls, and we know the type
of ACONST_NULL.
#KT-51718 Fixed
Previously it was like "null cannot be cast to MyObject" or
"MyObject cannot be cast to null", because `KClass.qualifiedName` is
`null` for local classes (including anonymous ones).
Use `KClass.toString()` instead, for both object actual dynamic type
and cast target type. This string representation is generally more
meaningful for such cases, and contains useful details for local
classes.
After commonization a type might additionally reference a abbreviated
type which is not present in the reference module's metadata.
This was even considered 'OK' before this commit, however only
under a special condition which might be too strict.
Right now, this newly introduced test will only enter the
newly allowed branch. This shall be re-reviewed later.

If the same NullableSingleInvocationCommonizer is reused for any reason,
it will store next inputs alongside previous, which is totally not
expected
^KT-51528 Fixed
Incorrect `valueParameter` was passed to `generateValueArgument`, which
resulted in incorrect type being considered for generating suspend
conversion.
#KT-50949 Fixed
Commonized type should match the platform's `platform.posix.ssize_t`
type alias' width. The implementation hard-codes platform widths for
all the targets, this can be potentially changed to search for ssize_t
in dependencies and get width from its type.
Use real targets in platform int commonization tests.

- Fix the predicate used for finding the member function `next`: check
that there's no extension receiver parameter, don't filter out
abstract functions.
- Do not copy iterator expression, instead change the type in all
references to the iterator variable.
- Fix some style issues.
#KT-47171 Fixed
Always serialize type table (and version requirement table) after
everything else, to prevent bugs like KT-51446 where inline class
underlying type was added to the type table after it has already been
serialized.
#KT-51446 Fixed
This is for simplification’s sake. We need to run executable file with --ktest_list_tests flag and compare test listing with the test listing produced during the compilation.
