[PATCH v3 0/3] MR773: vkd3d-shader/ir: Try harder to move `break's to the end of loops.

[Giovanni Mascellani (＠giomasce)]

~~This goes atop !764. The last three commits belong to this MR.~~

Since we want to get rid of loops and 'break's as much as possible, we try to move 'break's out of selection constructs as much as possible so it's easier to match them with loops. This MR introduces a few other tricks to help that.

--
  v3: vkd3d-shader/ir: Move breaks out of selections again after having optimized loops.
      vkd3d-shader/ir: Append code to the non-breaking branch if there is breaking one.
      vkd3d-shader/ir: Prepare for changing the destination list in vsir_cfg_optimize_recurse().
