instructions available as synthetic SDNodes PACKSS and PACKUS that will select to the correct instruction variants based on the return type. This allows us to use these rather important instructions when lowering vector shuffles. Also moves the relevant instruction definitions to be split out from the fully generic multiclasses to allow them to match these new SDNodes in the same way that the UNPCK instructions do. No functionality should actually be changed here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211332 91177308-0d34-0410-b5e6-96231b3b80d8
