- Now that the enum entry initializer provides a member scope, not the
enum entry, we need a way to get to the enum entry initializer in
tests. This can only be done via the enum entry's name, because the
initializer is anonymous.

In complex projects, there might be several library copies (with the
same or different versions). As there is no way to build a reliable
dependency graph between libraries, a project library depends on all
other libraries. As a result, there might be several declarations in the
classpath with the same name and signature.
Normally, K2 issues a 'resolution ambiguity' error on calls to such
libraries. It is acceptable for resolution, as resolution errors are
never shown in the library code. However, the backend, to which
'evaluate expression' needs to pass FIR afterwards, is not designed for
compiling ambiguous (and non-completed) calls.
Deprecate `unusedImports`, since they are supposed to be computed
on the IDE side from now on based on the information from
Analysis API
Currently the `unusedImports` property is not removed completely
so it can still be used by the Kotlin side import optimizer
tests; they should be moved/adapted to the intellij repository
also
As 'FirCodeFragments' are converted to IR independently of its context,
in some cases duplicate (and not quite correct) symbols for local
classes and functions are created.
Until properly fixed in fir2ir, here we replace such duplicates with
original symbols.
- `KtResolveExtension`s need to participate in active invalidation,
because LL FIR sessions depend on changes in resolve extension files.
- The resolve extension will simply be able to use the
`KotlinModificationSubscriptionService`, which is part of the Analysis
API surface for **API implementors**, to publish modification events.
- The commit refactors some modification trackers previously provided by
`KotlinModificationTrackerFactory` to a subscription-directed
mechanism implemented via `MessageBus` and `KotlinTopics`. The
following modification trackers are affected:
- Module out-of-block modification: The FE10 Analysis API doesn't use
these modification trackers, so the effect is limited to LL FIR.
- Module state: Likewise, FE10 doesn't use this modification tracker,
so again the effect is limited to LL FIR.
- Project and library modifications trackers remain, because many small
objects in e.g. light classes depend on these trackers (making
listener management unfeasible), and they are not relevant for
`LLFirSession` invalidation.
- This new API paves the way for a session invalidation service to
subscribe to out-of-block and module state changes as events. This
removes the need to iterate through modification trackers.
- Also note that the out-of-block modification provided by the new
subscription mechanism is intended to work for _any_ `KtModule`, as
long as it makes sense to have out-of-block modifications. For
example, the subscription should work for script modules. The OOB
modification tracker previously only supported `KtSourceModule`s,
which required separate single-file modification trackers for script
and not-under-content-root modules.
- `MessageBus` is a general utility provided by IntelliJ, but usually it
is retrieved from `project`. To keep these two concerns decoupled,
`project.messageBus` should not be used directly. Instead, the commit
adds a `KotlinMessageBusProvider`, which for now just provides the
project message bus with its standard implementation, but allows
swapping out the message bus implementation later.
- Global changes are also supported by the new subscription API. Such
global changes may for example occur during cache invalidation in
tests, on global PSI tree changes, or when an SDK is removed.
- Test-only invalidation has been moved from
`KotlinModificationTrackerFactory` to a new
`KotlinGlobalModificationService`. This creates one central service
for invalidation between tests, which is easier from an implementation
and a usage perspective than calling multiple scattered services and
providers.
The API replaces 'KotlinCompilerIde' in the IntelliJ IDEA plugin.
Code moved to Analysis API as its K2 implementation severely depends on
the internal compiler API (FIR).
The API is going to be used in the JVM debugger evaluator, and in
the Bytecode Tool Window.
In this commit, only ordinary Kotlin are supported.
In later commits, there will be also support for 'KtCodeFragment' files,
as well as some test coverage.
Use existing stub-based JVM library symbol provider for .knm and
.kotlin_metadata files. The only real difference is the scope filtering
by file types

We cannot always return null, because in such case some expressions
would become not fully explorable from the types perspective (see
the documentation on the `getCorrespondingTypeIfPossible`)
`FirNamedReference` might appear when resolving method references (like
`foo::bar`), but also when IJ Platform tries to resolve other parts of
the Kotlin PSI, notably a `KtNameReferenceExpression` in a
function call (`bar` in `foo.bar(baz)` expression).
N.B. FE10 implementation does not support returning `null` as a type -
currently it always returns `Unit` type in case it cannot figure out
the actual type. This issue should probably be tackled together with
KT-60166, so that both implementations are more or less aligned

This provider is responsible for answering queries related to resolve
extensions. At the moment, this includes retrieving a KtScope with all REx
top-level declarations (moved from KtSymbolFromResolveExtensionProvider), and
retrieving information necessary to supply a GeneratedSourcesFilter for REx
generated code. Future REx-related functions can be added to this interface.

- Add package and constructor listings
- Add single-scope renderForTests() implementation, including a lambda
to provide additional information about each symbol
- Remove special handling for empty scopes (interfered with single-scope
rendering)

Tests can now specify the code generated by a resolve extension from
within the test's testdata. Module-level directives control whether
resolve extensions are enabled for that module, as well as package names
and source shadowing regexes. File-level directives allow a `// FILE:`
block within the testdata to be converted into a KtResolveExtensionFile
and removed from the module as a whole. (This requires a new
`ModuleStructureTransformer`, because we need to be able to entirely
remove the files in question.)
Any test can add support for these directives by calling
`KtResolveExtensionTestSupport.configure` from within their
`configureTest` stanza. This allows this functionality to be used in
conjuction with any test base class.

Add a new method `isImplicitReferenceToCompanion` to determine
if the given reference is an implicit reference to a companion object.
The method is needed for the rename refactoring in IJ.

CompileTimeConstantProvider could receive a reference expression,
whose grandparent is KtTypeReference (seen that in UAST inspection).
FIR would not contain anything explicit for this reference,
FirResolvedTypeRef would be received as the nearest parent.
Of course, in this case, there could be no compile time constant anyway.
