    Reland "[strings] Fix raw hash lookup for forwarded strings" · 3cb7a814
    pthier authored
    This is a reland of commit 0a1f0e33
    
    Changes since revert:
    - Deferred label for loading from forwarding table.
    - Check if hash is computed instead of checking if it is a forwarding index.
    - Retreive hash from forwarding table only if hash is assumed to be computed.
    
    Original change's description:
    > [strings] Fix raw hash lookup for forwarded strings
    >
    > Raw hashes may need to be looked up via the forwarding table when
    > internalized strings are forwarded to external resources. Notably, the
    > megamorphic ICs were not correctly fetching the raw hash.
