Merge r256223 - [WebCore] Shrink Vectors passed to SharedBuffer
https://bugs.webkit.org/show_bug.cgi?id=207503
Reviewed by Yusuke Suzuki.
Once SharedBuffer::DataSegment is created, the content won't change in its life cycle. Shrink the passed vector
before assigning to member variable to save space.
With the quick research, when displaying Apple's website, 1~3% RSS usage reduction on PlayStation port.
No new tests because there's no behavior change.
