[JSC] Merge boolean fields in `JSRegExpStringIterator` into a single bitfield
https://bugs.webkit.org/show_bug.cgi?id=305258
Reviewed by Yusuke Suzuki.
The Global, FullUnicode, and Done fields are now stored as bit flags in a
single Flags field, reducing the object size from 56 to 40 bytes.
* Source/JavaScriptCore/builtins/RegExpStringIteratorPrototype.js:
(next): Use bitwise operations to read/write flags.
