Tune move instructions

Of the `move_dup` instructions, only `move_dup x x x` was
frequently used. Remove the other register combinations.

With those instruction `move_dup` instructions removed, it
is necessary to add new predicates to avoid unsafe translation
to `move_shift` and `move2_par`.

Also add additional transformations to transform more `move`
instructions into `move2_par`. The existing transformation
would require the `move` instructions to be in the "right"
order in order to be transformed.

Remove `move3 x y x y x y` because it turns out to be rarely
executed.
