[JSC] Use WTF::opaque to enforce structure address computation
https://bugs.webkit.org/show_bug.cgi?id=277008
rdar://132411354
Reviewed by Mark Lam.
In these particular functions, there is possibility that we end up keeping
StructureID (not Structure*) on the register / stack via ensureStillAliveHere.
Use WTF::opaque to enforce the computation of the address so that we can ensure
that address gets saved on the conservative roots.
