Support for "unsafe" cases of `finally`

[playXE]

Starlight needs support for code like this:

function foo() {
  try {
      return 1;
  } finally {
      return 2;
  }
}

Right now it returns 1 but should return 2.

Problem with implementing it is we down break and continue to single jumps which means finally can't be executed correctly and return is lowered to OP_RET which instantly returns, there could be one way to just jump to finally block on continue,break and return but this will not work as expected.
