We can terminate all the regions up to the last AST node in the stack, since regions without AST nodes are refinements of the region with the AST node, and should be terminated the same. This avoids leaving some regions that extend past e.g the `return` of a function. The region in the test case that changes here is: ``` [[@LINE+9]]:28 -> [[@LINE+12]]:4 : (0 - 1) ``` this was extending past the return. Now it is: ``` [[@LINE]]:6 -> [[@LINE+4]]:11 : (0 - 1) ``` Apologies, I also refactored the test case at the same time which makes the difference harder to see, but the main point is that this region now terminates at the return, the same as the others.
