Jitify the rest of ARM and x86 vertex morphs (not ready, just review)

This code is not well tested.  It does improve performance in Valkyria Chronicles 3 (while moving a character), but even when I had mistakes, I did not notice anything drawn wrong.  So I don't know if it is working right, and I have not tested it on any other games yet.

On x86, I also added SSE4.1 support, mainly to get rid of a comment.  It is slightly faster, but not majorly.  Also, in the cpu jit, switched a few memory copies to MOVD.
