Nikolay Lunyak 7541732752 [FIR] Fix TEST SPEC tests
Ensure the test data contents for both the frontends
are identical. This is needed for proper analysis of
K2-differences.

pyos e7b4927b6c FIR: don't emit SENSELESS_NULL_IN_WHEN when value is always null
This case (value is always null) contradicts the error message which says
"Expression under 'when' is never equal to null".

NONE_APPLICABLE instead of UNRESOLVED_REFERENCE_WRONG_RECEIVER
presumably because of the introduction of another `contains` extension overload

Tianyu Geng 263b876e6e FIR: extends scope of SENSELESS_COMPARISON
FE1.0 only reports SENSELESS_COMPARISON if one of the operand is `null`.
This change makes FIR reports also in case one of the operand has type
`Nothing?`.

In addition, fix handling of type alias in ConeTypeContext#isNullableType

Tianyu Geng c7272f6986 FIR checker: SENSELESS_(COMPARISON|NULL_IN_WHEN)
Currently DFA does not set "definitely equal to null" for access to variables that got assigned `null`. For example, FIR should mark the following line as SENSELESS_COMPARISON due to `s = null` above.
 https://github.com/JetBrains/kotlin/blob/d1531f9cdd5852352c0133198706125dc63b6007/compiler/testData/diagnostics/tests/smartCasts/alwaysNull.fir.kt#L6

The problem is at https://github.com/JetBrains/kotlin/blob/7e9f27436a77de1c76e3705da7aa1fbe8938336b/compiler/fir/resolve/src/org/jetbrains/kotlin/fir/resolve/dfa/FirDataFlowAnalyzer.kt#L1104

For null assignment, ideally the type should be `Nothing?`. This is
addressed in a followup commit instead.

Tianyu Geng 7bb81ef157 FIR: add equality call checker
Added checker for FirEqualityOperatorCall. It's surfaced as one of the
following diagnostics depending on the PSI structure and types under
comparison:

* INCOMPATIBLE_TYPES(_WARNING)
* EQUALITY_NOT_APPLICABLE(_WARNING)
* INCOMPATIBLE_ENUM_COMPARISON_ERROR

Comparing with FE1.0, the current implementation is more conservative
and only highlights error if the types are known to follow certain
contracts with `equals` method. Otherwise, the checker reports warnings
instead.

However, the current checker is more strict in the following situations:
1. it now rejects incompatible enum types like `Enum<E1>` and
  `Enum<E2>`, which was previously accepted
2. it now rejects incompatible class types like `Class<String>` and
  `Class<Int>`, which was previously accepted
3. the check now takes smart cast into consideration, so
  `if (x is String) x == 3` is now rejected
