[JSC] Use RegExpGlobalData::performMatch instead of RegExp::match for
RegExp.prototype.@@split
https://bugs.webkit.org/show_bug.cgi?id=244839
Reviewed by Darin Adler.
RegExp.prototype.@@split should update the following legacy RegExp static
properties[1][2][3]:
- RegExp.input
- RegExp.lastMatch
- RegExp.lastParen
- RegExp.leftContext
- RegExp.rightContext
- RegExp.$1, ... RegExp.$9
This patch changes RegExp.prototype.@@split to use
RegExpGlobalData::performMatch instead of RegExp::match.
This change ensures that the legacy RegExp static properties are updated.
