Offending PR is #7672 then

Note: This works with Accurate XFloat, but before it didn't require it to render properly

Dynasty Warriors: Gundam Reborn|BLES02057 have the same problem

Issue can be reopened, apparently the version I PR'd didn't solve this issue.

I can solve it now, but it will come with a noticeable performance loss. I think I can solve it without causing any performance loss at all, but it will take much longer to write. I'll probably work on some other stuff and revisit it at a later date.

For reference, One Piece was fixed by the FMA32x4 change and then rebroke with FM change

Its fixed now with spu llvm safe accurate xfloat isnt needed.
