Message:

IsExtensible should be a virtual method in the method table
​https://bugs.webkit.org/show_bug.cgi?id=154799

Reviewed by Mark Lam.

This patch makes us more consistent with how the ES6 specification models the
IsExtensible trap. Moving this method into ClassInfo::methodTable
is a prerequisite for implementing Proxy.IsExtensible.
