Because PackageViewDescriptor may consist of several package fragments from
different modules (see LazyPackageViewDescriptorImpl#fragments), we now filter
out fragments from irrelevant modules before rendering them into the .txt
The `@SinceKotlin("X.Y.Z")` annotation now hides a particular declaration from
resolution when the API version specified by the `-api-version` option is
_less_ than X.Y.Z. The comparison is performed as for versions in Maven:
MavenComparableVersion is in fact a copy of
org.apache.maven.artifact.versioning.ComparableVersion.
Also support "!API_VERSION" directive in diagnostic tests
#KT-14298 Fixed
Classifiers annotated with `@Deprecated(level = HIDDEN)` now have smaller
priority in imports, similarly to private classes. For example, if two
classifiers named Foo are imported with a star import and one of them is
deprecated-hidden, the name Foo in the source code is resolved to the other
one.
Also a minor change in multi-module diagnostic tests: do not append newlines
after the last module in the test
