    Original Commit Message:
    
        Compress the parameter count (and function length) stored in
        SharedFunctionInfo to a uint16_t. This limits us to 2^16 - 1 parameters
        per function, minus one for the "don't adapt arguments" sentinel value,
        which is one fewer than Code::kMaxArguments was already. Anyway, 65534
        arguments should be enough for anyone!
    
        This drops SFI size by 4 bytes.
