Better to use S000, etc. as that's more clear throughout.

Add back our older VFPU approximations, as fallbacks if files are missing.
...
PR #16984 added more accurate versions of these functions, but they require
large lookup tables stored in assets/.
If these files are missing, PPSSPP would simply crash, which isn't good.
We should probably try to warn the user somehow that these files are
missing, though...

This makes the results much more accurate to the PSP's results.
Could narrow a bit further swapping sin/cos/neg, which might be what the
hardware does given vrot.
