This change touches the following diagnostics to make them behave closer
to FE1.0
* SUPER_NOT_AVAILABLE
* SUPER_IS_NOT_AN_EXPRESSION
* INSTANCE_ACCESS_BEFORE_SUPER_CALL
* NOT_A_SUPERTYPE
Other than tweaking the diagnostics, this change also alters resolution
by consider marking `super` with mismatched type parameter as
errorenous. As a result, the following code no longer resolves.
```
class A: B() {
fun test() {
super<String>.length
// ^^^^^^ FIR currently resolves this to `String.length`.
// With this change, `length` becomes unresolved
// instead
}
}
```
Also, now we report `UNRESOLVED_LABEL` on unresolved label on `super`
reference, though FE1.0 reports `UNRESOLVED_REFERENCE`.
All the errors above are reported as ConeDiagnostics and hence some
checkers are deleted.
In addition, it also suppresses more downstream (mostly unresolved)
errors if the receiver has errors. FE1.0 doesn't do it for all the cases
we have here. But it seems nicer to reduce these "redundant" unresolved
errors.
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)
Specifically, the report the following 4 errors.
* NON_VARARG_SPREAD
* ARGUMENT_PASSED_TWICE
* TOO_MANY_ARGUMENTS
* NO_VALUE_FOR_PARAMETER
Also added/updated the following position strategies.
* NAME_OF_NAMED_ARGUMENT
* VALUE_ARGUMENTS
Currently, FIR reports errors caused by previous resolution failure. For
example with unresolved `a` and `b` in code `a.b`, both `a` and `b` are
highlighted. FE1.0 only highlights `a` since it's the root cause. This
change applies this heuristics when reporting FirDiagnostics.
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
They appeared, after the changes in previous commits at
org.jetbrains.kotlin.fir.resolve.transformers.body.resolve.FirExpressionsResolveTransformer#transformDelegatedConstructorCall
The idea is that dispatch receiver is available there in old FE, but additional
diagnostic should be reported on it (see KT-38813)
This change was not made intentionaly but it was the easiest way to
support new tower data elements structure and on the other side it's the
correct behavior as for old FE.
Also, if we once would prefer the previous behavior it's still not very
hard to support it
