Summary JSC: Workaround limited jump range on some CPU architectures

My recent change in https://bugs.webkit.org/show_bug.cgi?id=114577 introduced a "btpnz" to a branch target that is out of reach for some CPU architectures. In this case, it's simple enough to introduce the use of a jump island, and that saves us from having to change a whole bunch of CPU specific code. It works out to be a more optimal too. Patch coming soon.
