Similar to references to error type, this may happen if library A uses
an entity from library B annotated with an annotation from C, but A is
compiled without C on the classpath.
Nullability constraints should not be chosen when proper
argument constraints for variables in contravariant position present.

Force constraint system completer to always fix variable with unknown position.
This makes inferred type for in parameters less specific, but OI infers to
subtype in such cases, so NI won't infer to less specific types than before.
Current selection of completion mode for call is not always correct in case of full mode,
and sometimes too conservative in case of partial mode. Updated algorithm checks constraints
wrt position of type variables in return type and in other related constraints.
Full completion happens if proper constraint requirements are satisfied for variables.
'descriptor -> descriptor.original' relation is often inconsistent
wrt 'containingDeclaration', parameters, and type parameters,
we have to introduce some workarounds here.
- Fix `toString` evaluation for unsigned types in FoldConstantLowering
- make corner cases around float/double evaluation work for K/JS
- remove usage of kotlin type
The idea is the same as in case of anonymous objects: they are created only
from Kotlin code, so we are sure, that the parameters are valid.
Also, the inliner complains on their transformations.
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.
This allows us to not generate redundant immutable collection
stubs. The code to generate the immutable collection stubs does
not deal well with thinking that all external declarations
come from Java.
Because of incorrect flag we generated synthetic SAM candidates and got ambiguity when feature `SamConversionPerArgument` was enabled (Gradle case) because candidates for Java were duplicated
