[PATCH] PR19864: Revert r209764 in favor of the fix in r215766 (loop backedge jump attributed to confusing location when the last source line of a loop is inside a conditional)

[Adrian Prantl]

IMO, the best we can do is to use the end of the CompoundStmt as the cleanup location if there is one, and otherwise give up and use line 0.

```
if (c)
  foo(); // cleanups = line 0

if (c) {
}         // cleanups

if (c)
  foo();
else {
  bar();
}       // cleanups
```
