Refactor s8/s16 to float conversion.
...
It's pretty much all done the same way. Note that normals have always
been a little inconsistent between 127/128 and 32767/32768. But it's
probably not causing a major impact...

Force positions to scale by 128/32768 as psp does.
...
This makes everything use floats for positions. On some hardware/drivers,
this may be faster. On some it may be slower. We'll need testing to see
the performance impact.
Fixes Final Fantasy 4's pos misalignments, and probably others (like
Tekken 5 I suspect.)

Oops, the vertexdecoder should read vertex alpha.

Fix alpha channel in 565 morph on x86.
...
Shuffling is annoying, just do it on the other side. Fixes #5784 .

It's useful to know if we need to have a correct PC value or downcount.
