Before this commit, we compared property visibility with constructor
visibility only, which is incorrect. Now we compare property visibility
also with class visibility
#KT-19613 Fixed
Otherwise, e.g. in case of inner classes it may lead to
StackOverflowError:
- Someone tries to resolve supertypes
- We're starting building extends/implements lists
- Then calling resolve on the type references leads that some logic
in Java resolution again is trying to resolve supertype of the same
class (only in case of inner ones)
Probably, it could be fixed on the side of Java resolve
but at the same time it's clear that calling `resolve` while building
extends list it's really somewhat not very cool

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)
#KT-27895 Fixed
This test was originally written with fix for KT-22379
Lately, fix was proven to be wrong and reverted (KT-27084), which made
this test fail.
Correct solution here would be to mute test with link to YT issue, but
unfortunately we don't have infrastructure to mute tests locally (yet),
which is a major issue because this tests is a part of very popular for
local smoke-testing test suite (DiagnosticTestsGenerated).
