    Original change's description:
    > [builtins] Fix Array.p.join length overflow and invalid string length handling
    >
    > - Fixes and simplify allocating the temporary fixed array for ToString-ed elements.
    >   - When the array size is greater than representable by an intptr, it overflowed into a negative value causing a non-negative assert to fail.
    >   - Simplify fallback behavior by always allocating a conservatively sized temporary fixed array. Previously, if the array had dictionary elements, the temporary fixed array was sized based on %GetNumberDictionaryNumberOfElements() and then resized when entering the fallback.
    >
    > - Fixes related invalid string length handling. When the running total of the resulting string length overflowed or exceeded String::kMaxLength, a RangeError is thrown. Previously, this thrown RangeError bypassed JoinStackPop and left the receiver on the stack.
