Make B3 ccmp chain matcher use RAII
https://bugs.webkit.org/show_bug.cgi?id=315389
rdar://176792415
Reviewed by Keith Miller.
B3 ccmp chain matcher needs to roll back if a given pattern match fails
part way through. RAII is a more principled and less error prone way to
handle this.
Test: JSTests/stress/b3-ccmp-chain.js
* JSTests/stress/b3-ccmp-chain.js: Added.
