    This is a reland of 352b9ecb
    
    The test/fix CL has been merged in, as the fixes to return slot
    accounting are needed to fix Arm64 issues turned up by the fuzzers:
    
    https://chromium-review.googlesource.com/c/v8/v8/+/2644139
    
    The reverted fix for Wasm return slot allocation is added in
    patchset #2, to avoid fuzzer issues that it fixed:
