    [sfi] Compress function arg counts to 16 bit · 53d4dfc3
    Leszek Swirski authored
    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.
