056e0af55a Handle canonical form of e.g. 
vector_shuffle v1, v1, <0, 4, 1, 5, 2, 6, 3, 7>

This is turned into
vector_shuffle v1, <undef>, <0, 0, 1, 1, 2, 2, 3, 3>
by dag combiner.

It would match a {p}unpckl on x86.

4e99e6dfdd Ask legalize to promote all vector shuffles to be v16i8 instead of having to 
handle all 4 PPC vector types.   This simplifies the matching code and allows
us to eliminate a bunch of patterns.  This also adds cases we were missing,
such as CodeGen/PowerPC/vec_splat.ll:splat_h.

fc0a2ac06e TargetData.cpp::getTypeInfo() was returning alignment of element type as the 
alignment of a packed type. This is obviously wrong. Added a workaround that
returns the size of the packed type as its alignment. The correct fix would
be to return a target dependent alignment value provided via TargetLowering
(or some other interface).
