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.

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.

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 4726dcce40 FIR DFA: smartcast variable to Nothing? on null assignment
In order to make resolution still work for members not available from
`Nothing`, we track the type without `Nothing?` and use that for
resolution instead.
