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.

[NI] Restore missing smart casts after another smart cast in call

Expression type serves as a part of a key for retrieving smart cast info.
Rewriting expression type with SmartCastManager leads to incorrect processing of following smartcasts for same expression, therefore it was removed.
