Message:

Pass VM instead of JSGlobalObject to RegExp constructor.
<​https://webkit.org/b/122113>

Reviewed by Darin Adler.

RegExps don't need anything from the global object during their
construction and only use it to get to the VM. Reduce loads by
simply passing the VM around instead.
