Original issue's description:
> [date] Add ICU backend for timezone info behind a flag
> 
> This patch implements a timezone backend which is based on ICU, rather
> than operating system calls. It can be turned on by passing the
> --icu-timezone-data flag. The goal here is to take advantage of ICU's
> data, which is more complete than the data that some system calls expose.
> For example, without any special code, this patch fixes the time zone
> of Lord Howe Island to have a correct 30 minute DST offset, rather than
> 60 minutes as the OS backends assume it to have.
> 
> Unfortunately, the parenthized timezone name in Date.prototype.toString()
> differs across platforms. This patch chooses the long timezone name,
> which matches Windows behavior and might be the most intelligible, but
> the web compatibility impact is unclear.
