+instead of movsd from the stack.  This is actually not too bad to implement. The
+best way to do this is to implement a dag combine that turns 
+bitconvert(build_pair(load a, load b)) into one load of the right type.  The
+only trick to this is writing the predicate that determines that a/b are at the
+right offset from each other.  For the enterprising hacker, InferAlignment is a
+helpful place to start poking if interested.
