The code in IrTypeMapper was incorrectly translated from
KotlinTypeMapper during the development of JVM IR. The
`classDescriptor.hasBigArity` condition in KotlinTypeMapper was checking
if the class represents a function or a suspend function with big arity,
and the suspend function part was lost during conversion.
This resulted in incorrect generic signature being generated, which led
to malformed type exceptions from reflection, and compilation errors
from kapt stub generation.
Also, change a comment in irCodegenUtils to avoid confusion of numbered
function types (kotlin.jvm.functions.Function1, ...) with the big-arity
type kotlin.jvm.functions.FunctionN.
#KT-58375 Fixed
The tests are removed because JvmDefault is going to be deprecated with
error in KT-54746 and removed later in KT-57696.
Many of the removed tests already had existing counterparts with the new
modes `all` and `all-compatibility`. In this change, I've added such
tests where they were missing, and removed tests which were testing
behavior specific to the JvmDefault annotation, such as some
diagnostics.

during tail-call optimization.
There can be code, where all next instructions are non-meaningful and
there is a back-edge, for example, while(true){}. Previously, analyzer
incorrectly assumed, that this cannot happen. Now, it keeps track of
visited instructions and says, that there is no meaningful instruction
in such case.
#KT-56815 Fixed
These type parameters where used in function parameters,
but since suspendImpl is static function, it has no access
to class type parameters. Solution is to copy them to
the function itself.
#KT-55125 Fixed
Being disabled by default
and not well-documented, these functions cause confusion among early
adopters as to why their code don't work properly.
Assert APIs need a proper design across Kotlin platforms.
Since APIs are not available in common code and K/JS, it is premature
to have such a general feature in a new experimental platform.
Compiler tests:
* Mute tests that rely on assert.
* Replace JVM-specific assert calls with require calls and unmute passed K/JS tests.

in startCoroutineUninterceptedOrReturn. Otherwise, the coroutine will
not be interceptable later.
Add a test, which checks, that intercepted continuation is released.
#KT-55869
If the super class is in a file that has already been lowered, the base
method has an extra continuation parameter which breaks things.
Also, SAM wrappers around functional objects are tail-call and do not
need continuations ever, so don't even try.
^KT-50950 Fixed
We already check for {POP, Unit} sequence before ARETURN, but if the
there are multiple sequence before ARETURN, the compiler assumes, that
TCO misses.
The fix is to check, that the instruction after the sequence is either
ARETURN or another {POP, Unit} sequence.

instead of bytecode text ones. Check the content of continuation
object instead of bytecode, since this is less prone to changes during
changes in coroutines codegen.

1. merge(null of type A, null of type B) = null of unknown type;
2. merge(null of type A, something of type B) = merge(unknown null, B).
