Samuel Pitoiset abfd208cb0 nir: fix inserting the break instruction for partial loop unrolling
If the break in the original loop isn't in the first top-level if,
this would have re-inserted it in the wrong block.

Fixes this by re-inserting the break block to the corresponding break
block in the new loop by using the remap hashtable.

Deathloop and F1 2023 are affected but I'm not aware of any issues
for these two games.

Build & install
---------------

You can find more information in our documentation (`docs/install.rst

appropriate, you should ask your question on `OFTC's #dri-devel
<irc://irc.oftc.net/dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
