This commit contributes documentation that gives an overview of MethodHandles and VarHandles, and how it is implemented in the OpenJ9 JIT. The documentation covers the compilation pipeline from IL generation through optimization passes to code generation, focusing on the OpenJDK MethodHandle implementation used in Java 17+. It includes detailed explanations of key components such as MethodHandleTransformer, Known Object Table integration, call refinement strategies, inliner support, and VarHandle related optimizations.
