Summary DFG should support deep OSR

The runtime may realize that any further execution of a code block optimized by the DFG is impossible. We can make this work by jettisoning the code block and performing OSR even though the code block could be in use by any number of stack frames beneath the current one.

I originally posted this because I thought it would block https://bugs.webkit.org/show_bug.cgi?id=72312. But I've decided that the best way to do this is to avoid deep OSR altogether. Closing unless we find another reason why we need to do this.
