This uses the same approach as
INFERRED_TYPE_VARIABLE_INTO_EMPTY_INTERSECTION where we use a visitor
to find a call to a symbol that contains the type variable in question.
#KT-56140 Fixed
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)
Update includes:
- Changing syntax of `OI/`NI` tags from `<!NI;TAG!>` to `<!TAG{NI}!>`
- Fix some incorrect directives
- Change order of diagnostics in some places
- Remove ignored diagnostics from FIR test data (previously `DIAGNOSTICS` didn't work)
- Update FIR dumps in some places and add `FIR_IDENTICAL` if needed
- Replace all JAVAC_SKIP with SKIP_JAVAC directive
Mostly, these optimisations are picked from the old inference.
Also, remove exponential complexity for flexible types in approximation,
note that more correct fix for this would be to introduce new types
that corresponds just to platform types to avoid nullability problems,
but due to complexity it will be done later
