The previous CL https://crrev.com/c/1771783 introduced the old-to-new invalidation set, while still manually deleting slots in the remembered set. This CL only clears slots during sweeping when shrinking objects. The invalidation set is now used to filter slots in scavenge and mark-compact.

when wasm have multiple returns but not aligned such as return {kWasmI32, kWasmI64, kWasmI64, kWasmI32 } like test/wasm-api-tests/multi-return.cc do, wasm compiler will generate store instructions but not unaligned store instructions to store the return values, this will cause check failed on mips simulator, the test maybe will successful on mips native machine if the host kernel can handle the unaligend stores. This patch also fix the return address offset.

With the far jump table, we need to distinguish the maximum size of a single code space from the maximum total code size per module. On arm64, they differ, because we now support 1GB of code space, but each code space is still limited to 128MB.

This CL fixes a memory leak in the interpreter. The leak was caused by a cycle the object graph that was rooted with a global object. The cycle was the following: A global handle, owned by the interpreter -> reference stack of the Interpreter -> ref.func element (WasmExportedFunction) -> WasmInstanceObject -> WasmDebugInfo -> InterpreterHandle -> Interpreter With this CL we get rid of the global handle. Instead we store the stack in the WasmDebugInfo. We then have to load the reference stack every time we enter the Interpreter and want access the reference stack.

In the {Fixed} variant, the {WasmCodeManagerTest} always reserves 1GB of memory. This makes the test run OOM on many 32-bit platforms. Instead of skipping it selectively, this CL just removes the whole test. It caused a lot of trouble in the past, and needs two test-only methods in the WasmCodeManager. Also, the {Fixed} variant will not be needed any more with the wasm far jump table, since modules can always grow then. Drive-by: Clean up the unittests status file a bit.
