Several exception related stress tests crash when ran with the flag wasmOMGOptimizationLevel set to 0. Some of the failing tests in JSTests/wasm/stress/ are cc-int-to-int-cross-module-with-exception.js, exception-liveness-tier-up.js, exception-trap.js, simd-exception.js, exception-multiple-instances.js, among others. The tests crash with ASSERTION FAILED: m_offset + sizeof(T) <= m_size, from the DeltaCompresseionReader::read().
