    [wasm] Use a consistent hash for wire bytes · 918b46af
    Clemens Backes authored
    We use a hash for different things:
    - dumping wasm module to file,
    - generating the script name, and
    - computing prefix hash / wire byte hash for caching.
    
    Two of them were using the StringHasher, one use base::hash_range.
    For experimental PGO support, we will also need a hash value, so unify
    this to use the same hash everywhere.
    Since the result of base::hash_range is platform-dependent, use the
    StringHasher everywhere.
