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)
Since we skipped trivial constraint with `Any?` from parameter type of
function `equals`, the compiler thought that there is no proper
constraints (upper bounds do not matter here) and marked resolved
call as a failed one, then diagnostic about missing equals was added
Also, tune `TrivialConstraintTypeInferenceOracle` for `Any?`-like
constraints
