Moved CryBoy into the crab codebase, along with all associated changes
...
The next step will be abstracting features between the two, like the
scheduler, apu, display, and anything else than can be abstracted. Once
this is abstracted, I can go back to trying to fix the CryBoy APU that
started having trouble once it was on the scheduler. This will ensure
consistency between the two projects.

move step_arm ldm/stm logic back to post-instruction, fix golden sun issues
...
This was causing battles and entering the overworld to fail. I saw a
`stmdb r1, {r0, r2, r3, r4, r5, r6, r7, r8, sb, sl, fp, ip}` while r1
was `03000380` and the currently executing instruction was `03000348`.
This means that the store would write over `03000350`, which is the
instruction being read. Because I had incremented r15 _ahead_ of the
instruction, this caused the pipeline to store the wrong values when the
write near r15 was detected. This changes moves the stepping logic back
to _after_ the instruction, and handles the r15 +12 case directly
