Move 'generateExpressionForReferencedDescriptor' to CallGenerator,
use it in 'generateCall',
add PSI-free versions of some utility methods so that call elements can
be generated when we're already deep in ResolvedCall generation
and have forgotten about PSI.
Before this change such wrapping happened only during coercion,
i.e. when a call-site expected a KClass instance.
But when call-site expects Any, for example, no wrapping happened,
and raw j.l.Class instance was left on stack.
The solution is to put wrapping code closer to generation of annotation's
method call itself to guarantee that necessary wrapping will happen.

When synthetic member comes not from the receiver type itself,
but from one of its supertypes it doesn't make sense to subsitute
the member with receiver type, we should obtain relevant supertype
and use it instead.

Set constructor return type in FunctionDescriptorResolver#createConstructorDescriptor
(it seems to be the only place where ClassConstructorDescriptorImpl#initialize(...)
is called, but returnType is not set).
When there is unsuccessful (e.g invisible) result of one kind (static/non-static)
and there is a successful candidate for another kind, choose the latter one.
Note, that we have to postpone commiting trace until we choose one of the results,
otherwise errors of unsuccessful results are reported
TODO: Maybe it makes sense to report all results when all of them are
unsuccessful (NONE_APPLICABLE or something like this)
#KT-16278 Fixed
Expression '1.unaryMinus()' is resolved as Int::unaryMinus call with Int receiver.
However, this expression is implicitly coerced to a different integral type (Byte, Short, Long)
based on results of constant evaluation.
Introduce IMPLICIT_INTEGER_COERCION type operator to handle such cases.
TODO: should we use it for simple constant expressions like '1' and '-1'?
Previously ReflectionTypes.find returned an error class in case a class
is not found in the module dependencies. The problem with this approach
is that each call site should call ErrorUtils.isError on the result and
report an error if needed, in order to stop this type from reaching the
codegen, which can't handle error types.
Now we create a MockClassDescriptor instance instead. It's not an error
class, so it'll be handled correctly in the codegen. Also its scope is
empty and errors are reported on any non-trivial usage (see
MissingDependencyClassChecker), so this approach is not worse than error
classes

Finnaly markers are used only for non-local return processing and are removed after inlining to non-inline functions, same deletion should be performed on inlining to anonymous objects
#KT-16532 Fixed
The problem was that he number of mask parameters for defaults when
generating methods declaration was being calculated upon resulting signature
(with additional parameters: extension receivers, enum name/ordinal),
while on call-sites the masks number was calculated by the arguments number
in resolved call, i.e. by the number of real value parameters.
And because of the additional synthetic parameters (like enum.ordinal) these
two numbers could be different.
The solution is just to use value parameters number in both places.
Note, that we only count value parameters from the original sourse
declaration, ignoring synthetic ones generated by backend (e.g.
Continuation for suspend functions)
#KT-14565 Fixed
See the issue and the test. The problem was that when generating
call to `foo` method in member scope of `AT<*>` its resulting descriptor
after substitution and approximation was: fun foo(x: Nothing..Array<out Nothing>).
This signature is correct, but when using this parameter type
for generating a vararg argument the assertion is violated that
the type of the argument must be an array
(by default we're using lower flexible bound everywhere)
The solution is using upper bound for flexible types that should
always have a form of Array<out T> for varargs (even for such corner cases)
both for Kotlin and Java declarations.
#KT-14607 Fixed
The problem was that LanguageVersionSettingsImpl.DEFAULT did not have
"WarnOnCoroutines" as a feature and so it was manually added to the settings,
but only in two places: in the compiler and in the IDE
The problem was that when obtaining char from the wrapper,
codegen used int as expected type that led
to a ClassCastException: java.lang.Character cannot be cast to java.lang.Number
The solution is using coercion to chars, it's still correct,
because of implicit widening coercion in JVM from C to I
#KT-15105 Fixed
The problem was that in `Function<T>.apply(T)` T is now not-platform,
so when checking if not-null assertion is needed for parameter in SAM,
it's defined by the upper bounds of T that is a platform (Any..Any?),
and while it's definitely not marked as nullable it's still nullable
in a sense that it can contain null as a value.
So the solution is obvious
#KT-16413 Fixed
In most of the cases it was used together with CLASS_ONLY and vice versa
They only case when CLASS_ONLY was used without INNER_CLASS
is possibleParentTargetMap.COMPANION_KEYWORD.
But after diagnostic NESTED_OBJECT_NOT_ALLOWED has been introduced,
there's no sense in the restriction of exactly the companion's parent
For clarification see test data changed
The problem was that anonymous classes wasn't regenerated
although they capture another anonymous class that is a subject
for regeneration
