Description
The idea is to automatically determine when variables can go out of scope because they are no longer needed. (Relying on a live variables analysis.)
There is another question here: does this optimization buy us anything or does clang or gcc already do this for us automatically?

Research direction
No file or test is named; start by locating the live variables analysis and reviewing how variable scopes are represented in the compiler. Check whether clang or gcc already provide the proposed optimization, then define and validate the pass only if it provides a measurable benefit.
