Log Message:
-----------
[JSC] `RegExp::deleteCode()` should not clear the pattern's atom
https://bugs.webkit.org/show_bug.cgi?id=323838
Reviewed by Yusuke Suzuki.
m_atom and m_specificPattern depend only on the pattern, like
m_numSubpatterns and m_rareData which deleteCode() already keeps, so stop
clearing them.
