      [wasm] Stricter max memory check · a5449b0f
      Clemens Hammacher authored
      If the maximum number of memory pages is raised using
      --wasm-max-mem-pages, we might allocate more than kMaxInt bytes for
      wasm memory. The byte length is stored as int in JSArrayBuffer, hence
      this can lead to failures.
      Thus, we now additially check against kMaxInt, and fail instantiation
      if this check fails.
      
      Drive-by: Add/fix more bounds checks.
