78e3d565af INSERT_VECTOR_ELT lowering bug: 
store vector to $esp
  store element to $esp + sizeof(VT) * index
  load  vector from $esp
The bug is VT is the type of the vector element, not the type of the vector!

or custom lowering fails.

6be79823e7 * 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.

87f080949b 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.

8e1fcab2bc Scalarized vector stores need not be legal, e.g. if the vector element type 
needs to be promoted or expanded.  Relegalize the scalar store once created.

handling cases where the vector elements need promotion, expansion, and when
the vector type itself needs to be decimated.

1d2e995fc1 Lower BUILD_VECTOR to VECTOR_SHUFFLE if there are two distinct nodes (and if 
the target can handle it). Issue two SCALAR_TO_VECTOR ops followed by a
