coroutines intrinsic lambda.
The logic is if the lambda is crossinline we need to generate the
accessor. However, suspendCoroutine's and
suspendCoroutineUninterceptedOrReturn's parameter, despite being
crossinline, are effectively inline. Thus, we do not need to generate
the accessor.
#KT-27503 Fixed
In 1.3.31 I fixed Java interop for inline function with coroutines
(TL;DR: when we need a state machine, generate two methods: one with
normal name, and the other one with $$forInline suffix, for the inliner
to use, just like inline suspend functions), however, I forgot a case
with inline suspend function with inline suspend function parameter.
In this case, the compiler a generated two functions, as needed, but,
neither of them had a state-machine. This change adds the state-machine
for the method with normal name. Note, that suspend inline functions
with crossinline parameter, which are also supported by the change,
did not cause incorrect behaviour, since until now they were generated
as synthetic.

This fixes Java interop of inline functions, which use coroutines.
However, we cannot transform the state-machine. Thus, we generate
a $$forInline counterpart for suspend functions (similar to inline
suspend functions) and invokeSuspend$$forInline for lambdas if these
coroutines are going to transformed (i.e. are declared inside inline
functions).
During transformation we just skip method with state-machine and
transform the $$forInline counterpart. Of course, if inline site is
inline itself, we generate both state-machine version (which will be
dropped during the next transformation) and $$forInline version.
Consequently, the final version of the coroutines will not have
$$forInline counterpart.
Unfortunately, since CompileKotlinAgainstInlineKotlin tests do not allow
java sources, the tests for the interop are usual box tests.

This directive generates TailCallOptimizationChecker in package helpers.
The check for tail call optimization is based on coroutine stack traces
bug (feature?): when tail call optimization hits, the continuation
object is not generated. Thus, there is no debug metadata for this
suspend function. Consequently, the coroutines stack trace does not
contain stack trace element for that function.
This check is performed by TailCallOptimizationChecker.
Since this is runtime check, unlike bytecode tests, it does not require
test data adjustments on each codegen or inliner change.
Since the check is based on debug metadata, which is JVM specific, there
is not support for other backends yet.
Use `// !LANGUAGE: -ReleaseCoroutines` instead in tests which require
old (1.2) coroutines, and nothing in tests which require new coroutines
because master is already 1.3. Also remove superfluous API_VERSION and
other directives which have no effect anymore. Do not include runtime
automatically with `WITH_COROUTINES`/`COMMON_COROUTINES_TEST` in box
tests; require `WITH_RUNTIME` for that (majority of tests already had it
anyway), but remove it from bytecode text tests where runtime is always
added automatically. Fix the coroutine package selection code in
KotlinTestUtils and update the bunch files correspondingly.
Disable tests in `box/coroutines/noStdLib` on JVM: despite the name,
these tests were launched with stdlib because of the code in
CodegenTestCase, and they do not work without it because at least
CoroutineUtil.kt requires stdlib to compile correctly
Most of these tests used this directive as a way to opt in to a new
language feature, and most of those features are already stable for a
long time, so no opt-in is needed. Some other tests used the directive
to opt out from a language feature, replace those by the `LANGUAGE`
directive. One test used the directive to test behavior that actually
depended on the API version; use `API_VERSION` directive there instead.
Return type is not needed for checking overloads, but querying it may
involve resolving function bodies, which usually happens after overload
checking (see LazyTopDownAnalyzer.analyzeDeclarations) and at this point
can lead to incorrect BACKING_FIELD_REQUIRED value being computed for
some properties (see KT-27895)

Check, that all suspension points are immediately followed by ARETURN
and do not check that all these ARETURNs are immediately preceded by
suspension points.
#KT-27190 Fixed
Reflection expects to see a callable method for a hidden constructor,
thus, it should be a synthetic accessor.
JVM method signature in metadata should point to the synthetic accessor.
Annotations for hidden constructor should be written on the synthetic
accessor.
<IMPL_SUFFIX> for method is a method signature hash,
if method value parameter types contain inline class types,
otherwise 'impl'.
Constructor methods are named as 'constructor-<IMPL_SUFFIX>'.
Synthesized 'box' and 'unbox' methods are named as
'<METHOD_NAME>-<IMPL_SUFFIX>'.
Erased implementations of overriding and non-overriding methods
are named as '<METHOD_NAME>-<IMPL_SUFFIX>'.
Fully specialized implementation of 'equals' will have a special suffix.
