New tests are red in current commit!
All `.ll.kt` files are just copies of `.fir.kt` or `.kt`. This will be
fixed in the next commit to clearly show difference between LL and FIR.
The original purpose of this change was to test
`ACTUAL_ANNOTATIONS_NOT_MATCH_EXPECT` diagnostic, for which FIR checker
will be run only in IDE (to be changed in next MR), so its reports
a lost from usual KMP tests.
But this looks like a useful change for all KMP tests, not only this
diagnostic.
