4352cc9e21 * Add supprot for SCALAR_TO_VECTOR operations where the input needs to be
promoted/expanded (e.g. SCALAR_TO_VECTOR from i8/i16 on PPC).
* Add support for targets to request that VECTOR_SHUFFLE nodes be promoted
  to a canonical type, for example, we only want v16i8 shuffles on PPC.
* Move isShuffleLegal out of TLI into Legalize.
* Teach isShuffleLegal to allow shuffles that need to be promoted.

bc70cf8be9 Implement the Expand action for binary vector operations to break the binop
into elements and operate on each piece.  This allows generic vector integer
multiplies to work on PPC, though the generated code is horrible.

the vector type itself needs to be decimated.
