[JSC] Use cooperative driving in TLA modules
https://bugs.webkit.org/show_bug.cgi?id=319867
rdar://182767755
Reviewed by Yijia Huang.
This patch extends support of cooperative driving to cover TLA modules.
The core change is accepting JSModuleRecord as a driver. And the change
is really minimum. The benefit is now bytecode generation becomes
simpler since we can always use the cooperative driving code.
