It's a common compiler argument and may be applied to any compile task, there's no reason to set it separately for K/JS and K/JVM, and now it sets the compiler argument for metadata compilation tasks as well
The problem was that we were using unenhanced constructors that still
might contain java type refs.
Basically, most of the `firClass.declarations` usages are unsafe in that
meaning.
The test is very complicated because to reproduce the exception there
should be some conditions met:
- MyClass should be compiled with K1, so it has `@EnhancedNullability`
annotation serialized (that is unnecessary, but don't do any harm)
- `@Nls` scope should be properly resolved, so enum entries are converted
to resolved type refs
- That leads to attempt to check if null-check might be needed to be
inserted and to failure at FirTypeUtilsKt.getCanBeNull
While this quite controversial to have this check being performed for
freshly created annotations calls, the problem with improper constructor
lookup anyway existed and fixed correctly.

In a lot of cases, when we want to process the
declaration in scope, it should be resolved to at least TYPES phase.
To avoid doing it manually in all our variety of scopes, we do it when the scope it created.
It was implicitly working manually before as lazy resolve did a lot of extra work
on resolving a declaration it was not supposed to resolve.
Now it's not the case, and we have to explicitly resolve all the declarations we need.

1. Leaving no unbound symbols in the IR tree, KT-54491:
- All unbound symbols are bound to synthetic stub declarations
- Improved detection of the root cause for every partially linked classifier
- Improved error messages
2. Visibility valiation, KT-54469
3. Always check deserialized symbols:
If the deserialized symbol mismatches the symbol kind at the call site in the deserializer then generate and reference another symbol with the same signature. In case PL is off, just throw IrSymbolTypeMismatchException.
4. Handle class inheritance violation:
- Detect illegal inheritance (ex: inheriting from a final class)
- Detect invalid constructor delegation (ex: delegating to another class than the direct superclass)
- Simplification: Reduce the number of PartialLinkageCase subclasses
- Reworked error message generation to have shorter and clearer messages
5. Handle class transformations and all known side-effects, examples:
- nested <-> inner
- class <-> enum/object
- adding/removing subclasses of sealed class
- adding/removing enum entries
6. Check direct instantiation of abstract class.
Such instantiation could be possible if a class was non-abstract in the previous version of a library.
7. Handle unlinked annotations on declarations.
Such annotations are removed from the IR. The appropriate compiler error message is produced for every individual case.
8. Handle value argument count mismatch at call sites
9. Handle calling suspend function from non-suspend context.
This could happen if a suspen function was non-suspend in the previous version of a library.
10. Handle overriding inline callables.
Only the leaf final callable can be marked with `inline`.
11. Detect illegal non-local returns from noinline/crossinline lambdas.
With the partial linkage turned on it's hard to predict whether a newly created IrSymbol that is added to the SymbolTable via one of referenceXXX() calls will or won't be bound to some declaration. The latter may happen in certain cases, for example when the symbol refers from an IR expression to a non-top level declaration that was removed in newer version of Kotlin library (KLIB). Unless such symbol is registered as "probably unbound" it remains invisible for the linkage process.
The optimization that allows to reference symbols without registering them as "probably unbound" is fragile. It's better to avoid calling any referenceXXX(reg = false) functions. Instead, wherever it is s suitable it is recommended to use one of the appropriate declareXXX() calls.
For the future: Consider implementing the optimization once again for the new "flat" ID signatures.
Also: Temporarily mute assertion that checks symbols overwrites in SymbolTable ^KT-57049
