Mikhail Zarechenskiy bcc8802014 [NI] Avoid constraints from expected type for effectively empty system 
Expression will be checked against expected type later.

 Theoretically, this is not very good, but it aligns with the old
 inference, plus it helps avoiding multiple type mismatch diagnostics.

Mikhail Zarechenskiy 9891f562cc [NI] Make subtyping algorithm more robust to error types 
During subtyping/incorporation we transform types (e.g. changing nullability,
 form of the type) and, basically, we're doing this to some FIXPOINT.
 It's important that we use `KotlinType.hashCode()` to compare types, but
 for error types hashCode is a hashCode of its supertype and, for example,
 `makeNullableAsSpecified` method recreate type every time. So, we continue
 to generate new constraints and we'll never stop incorporation algorithm

Dmitry Savvinov 2d8e4e752c Fallback to Any type in case supertypes are empty 
This can happen e.g. if all supertypes were on the cycle (A : B, B : A)
-- then SupertypesLoopChecker will cut all supertypes that are on cycle,
leaving set of supertypes empty.

Some clients in the compiler are not ready to work with empty list of
supertypes -- notably, CommonSupertypes.

Dmitry Savvinov 58b815d842 Fix false USELESS_CAST in function with expression body 
Note that current behaviour is made similar to the case with
properties initializers/accessors, which means that more complex
cases are not covered yet (see KT-20801) #KT-20802 fixed.

Denis Zharkov 257417bc4a Minor. Lower type aliase declarations priority 
There are several reasons for doing this:
- See org.jetbrains.kotlin.serialization.deserialization.descriptors.DeserializedMemberScope.computeDescriptors,
  classifiers are being deserialized in the last turn, so it's necessary to preserve consistent order
- Their priority should be close to classes
