See hrydgard#5549. Matches tests for various prefix settings.
Very similar to vsop, just with a bit more fixed values.
Verified by tests. Also, confirmed that the old vxbz encoding had no output, but the new position (as used by gas) does.
Not sure any games actually use them, but good to have the remaining vfpu ops all implemented.

Very nicely investigated! This makes a ton of sense, of course. |

I've become suspicious of vbfy's prefix handling, but haven't tested it yet.Indeed, vbfy does this too. This explains much weird prefix behavior.Previously I had tested prefix handling on vscl, and it behaved strangely when used with t. Now it seems obvious that regnum swizzle was fixed, and probably explains why constants seemed to behave strange.
Also added vsbz/vlgb based on tests (they are pretty straight forward.) Didn't really test prefixes with them, though.
