David Green 9ee7075ca5 [ARM] Match dual lane vmovs from insert_vector_elt
MVE has a dual lane vector move instruction, capable of moving two
general purpose registers into lanes of a vector register. They look
like one of:
  vmov q0[2], q0[0], r2, r0
  vmov q0[3], q0[1], r3, r1
They only accept these lane indices though (and only insert into an
i32), either moving lanes 1 and 3, or 0 and 2.

This patch adds some tablegen patterns for them, selecting from vector
inserts elements. Because the insert_elements are know to be
canonicalized to ascending order there are several patterns that we need
to select. These lane indices are:

3 2 1 0    -> vmovqrr 31; vmovqrr 20
3 2 1      -> vmovqrr 31; vmov 2
3 1        -> vmovqrr 31
2 1 0      -> vmovqrr 20; vmov 1
2 0        -> vmovqrr 20

With the top one being the most common. All other potential patterns of
lane indices will be matched by a combination of these and the
individual vmov pattern already present. This does mean that we are
selecting several machine instructions at once due to the need to
re-arrange the inserts, but in this case there is nothing else that will
attempt to match an insert_vector_elt node.

This is a recommit of 6cc3d80a84884a79967fffa4596c14001b8ba8a3 after
fixing the backward instruction definitions.
