/**
* This provider allows to get symbols for so-called built-in classes.
*
* Built-in classes are the classes which are considered mandatory for compiling any Kotlin code.
* For this reason these classes must be provided even in a case when no standard library exists in classpath.
* One can find a set of these classes inside core/builtins directory (look at both src/kotlin and native/kotlin subdirectories).
* In particular: all primitives, all arrays, collection-like interfaces, Any, Nothing, Unit, etc.
*
* For non-JVM platforms, all / almost all built-in classes exist also in the standard library, so this provider works as a fallback.
* For the JVM platform, some classes are mapped to Java classes and do not exist themselves,
* so this provider is mandatory for the JVM compiler to work properly even with the standard library in classpath.
