AArch64: compare correct type for multi-valued SDNode.

If Orig produces more than one value (rare) with different types (rarer) then
we need to make sure we check against the one that Orig actually represents,
not just the first type.

Unfortunately because of the combination of things that need to happen I wasn't
able to produce a test.
