We are going to deprecate `WITH_RUNTIME` directive. The main reason
behind this change is that `WITH_STDLIB` directive better describes
its meaning, specifically it will add kotlin stdlib to test's classpath.
The main idea is the following: since we need to generate
(fake)continuations before inlining, we move IrClasses of suspend
lambdas and continuation classes of named functions into the functions.
Thus, it allows the codegen to generate them prior to inlining and
the inliner will happily transform them for us.
Because of that, lowerings which transform call-site function are likely
to change reference to lowered suspend lambdas or functions.
Hence, do not rely on references to lowered suspend lambdas or
functions, instead, rely on attributes.
Do not generate continuation for inline suspend lambdas.
Previously, inline suspend lambdas were treated like suspend functions,
thus we generated continuations for them. Now we just do not treat them
as suspend functions or lambdas during AddContinuationLowering.
We should add continuation parameter to them, however.
Do not generate secondary constructor for suspend lambdas, otherwise,
the inliner is unable to transform them (it requires only one
constructor to be present).
Generate continuation classes for suspend functions as first statement
inside the function.
This enables suspend functions in local object inside inline functions.
Since we already have attributes inside suspend named functions, we
just reuse them to generate continuation class names. This allows us
to close the gap between code generated by old back-end and the new
one.
If a suspend named function captures crossinline lambda, we should
generate a template for inliner: a copy of the function without
state-machine and a continuation constructor call. The call is needed
so the inliner transforms the continuation as well.
Refactor CoroutineTransformerMethodVisitor, so it no longer depends on
PSI.
in OUTERCLASS field.
The inliner generates two versions of suspend functions/lambdas in
inline functions: with state-machine and without. The former is used
to call the function from Java or via reflection and have ordinary
name, while the latter is used by inliner and have $$forInline suffix.
The inliner throws the state-machine version away, duplicates
$$forInline version and then call state-machine generator.
If these suspend functions/lambdas are not going to be inlined,
$$forInline version is not generated. However, all objects, which are
used in these suspend functions/lambdas, have $$forInline version
written to OUTERCLASS field. This leads to errors by proguard.
Since they are used in both state-machine version and for-inline ones,
we can simply remove $$forInline suffix from OUTERCLASS field and this
fixes the issue.
