This reverts commit 1eecdf3450.
Reason for revert: unacceptable binary size increase (+65.5 KiB)
We’ll reland once we implement a more efficient way to store the
sequences.
Original change's description:
> Update RegExp sequence property support
>
> This patch aligns --harmony-regexp-sequence with the latest version of
> the corresponding TC39 and Unicode proposals.
>
> The list of supported properties has been changed:
>
> - https://github.com/tc39/proposal-regexp-unicode-sequence-properties#proposed-solution
> - https://unicode.org/reports/tr18/#Full_Properties
>
> Furthermore, the Unicode data now uses Unicode v13.0.0 instead of v12.0.0.
>
