This directive anyway does not make test run twice with OI, and with NI
It only once run the test with specific settings (// LANGUAGE)
and ignores irrelevant (OI or NI tags)
#KT-36247 fixed
A lot of testdata changed because significanly less (error) descriptors
are created for unresolved types, so diagnostics became different.
- locals win
- unary calls to plus/minus are not supported in favor of unaryPlus/unaryMinus
- unqualified nested classes are temporarily reported as unresolved
- function without receiver win against extension function
- explicit import win against star import
