- Our current FIR caches are based on `ConcurrentMap` and thereby do not
support size and lifetime limits out of the box. For example,
first-layer caches with a limited size can speed up access of the most
frequently used elements, while having a small memory footprint.
- Caffeine is a modern and well optimized caching library that allows us
to create thread-safe and performant caches with various size or
lifetime limits.
- The cache must support concurrency because session components such as
symbol providers may be accessed concurrently once parallel resolve in
the Analysis API has been implemented (see KT-55750). Caffeine caches
support concurrency.
* Replace pcollections with ClassValue/ConcurrentHashMap-based caches
* Do not store weak references, instead cache strong references and count on ClassValue to unload the corresponding classloader if necessary
* ConcurrentHashMap does not rely on WeakReference as it's only selected on Android where classloader leaks don't exist
* Update reflect/scripting JDK requirement to Java 8 in order to proceed

This template provides all infrastructure to write Kotlin scripts for
build regression benchmarks. These benchmarks will use gradle-profiler
to run provided scenarios on user projects. All benchmark results
in the script then will be aggregated into single one showing
difference between them.
Generally such kind of benchmarks should be used to track early Gradle
build regressions between releases.
^KT-49921 In Progress
Intended to be used by Kotlin/Wasm compiler.
Includes:
* IR tree: declarations, instructions, types.
* Convertors: ir2text, ir2bin, bin2ir
* Spec tests, to test convertors against reference Wabt tool
Somehow an Apache-2.0 license notice with a JetBrains copyright that had
been pasted in the middle of the LGPL license text.
This removes this notice and restores the pristine, unmodified license

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
