This PR fixes lowering of the next code: ``` void foo(int x, int y) { switch (x) { case 0: if (y) break; break; } } ``` i.e. when some sub statement contains `break` as well. Previously, we did this trick for `loop`: process nested `break`/`continue` statements while `LoopOp` lowering if they don't belong to another `LoopOp` or `SwitchOp`. This is why there is some refactoring here as well, but the idea is stiil the same: we need to process nested operations and emit branches to the proper blocks. This is quite frequent bug in `llvm-test-suite`
