Add support for building a ScheduleDAG from MachineInstrs. This is currently
fairly conservative; it doesn't do alias-analysis queries and it doesn't
attempt to break anti-dependencies.

Simplify SplitVecRes_EXTRACT_SUBVECTOR.  This means
that it no longer handles non-power-of-two vectors.
However it previously only handled them sometimes,

the index and vector type.  For example, for a vector
of length 6, it would succeed if and only if the

In ScheduleDAGRRList::CopyAndMoveSuccessors, create the SUnit for the load
before creating the SUnit for the operation that it was unfolded from. This
allows each SUnit to have all of its predecessor SUnits available at the time
it is created. I don't know yet if this will be absolutely required, but it
is a little tidier to do it this way.
