Subject: [PATCH] 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).
