This includes all the collision stuff needed to spawn `target`,
decompiles the sparticle code and adds some of the PC hacks needed for
merc to run (it doesn't work quite right and looks bad, likely due to a
combination of code copied from Jak 2 and the time of day hacks).
There are a bunch of temporary hacks (see commits) in place to prevent
the game from crashing quite as much, but it is still extremely prone to
doing so due to lots of missing functions/potentially bad decomp.

Small fix to decompiler when the original compiler uses `ra` register.
This seems to happen in "normal" code very rarely - perhaps they
manually specified this in an `rlet`.
Start figuring out buckets/textures for Jak 3.
The foreground code is not yet modified for PC - I want to wait until
the game is running, since it is too hard to do it now.
