Contributions summary:Varun primarily focused on improving the performance and reliability of the Eclipse OMR runtime. Their work included disabling assertions in example code, integrating Valgrind for memory checking, and optimizing memory management by introducing a memory heap range map and later switching to using handle->getMemoryBase(). They also addressed memory-related issues by adding valgrind calls in various parts of the code and fixing errors related to object allocation and freeing, which significantly improved the reliability of the garbage collector. Further improvements involved the use of STL.
