    Reland "[wasm] Re-exported globals preserve their identity" · 1e4282db
    Andreas Haas authored
    This is a reland of f7a1932e
    
    There was a wpt test in Chrome that expected the incorrect behavior.
    I disable the test in https://crrev.com/c/2264418 so that we can land
    the fix here.
    
    Original change's description:
    > [wasm] Re-exported globals preserve their identity
    >
    > V8 fails a recently added spec test that when an imported global get
    > re-exported, it should preserve its identity. This CL fixes the behavior
    > in V8.
    >
    > Drive-by change: fix the object printer of globals: a global which
    > stores a reference type only has a tagged buffer, a global which stores
    > a value type only has an untagged buffer.
