This patch adds support for the following new instructions in the Power ISA 2.07: vpksdss vpksdus vpkudus vpkudum vupkhsw vupklsw These instructions are available through the vec_packs, vec_packsu, vec_unpackh, and vec_unpackl built-in interfaces. These are lane-sensitive instructions, so the built-ins have different implementations for big- and little-endian, and the instructions must be marked as killing the vector swap optimization for now. The first three instructions perform saturating pack operations. The fourth performs a modulo pack operation, which means it can be represented with a vector shuffle, and conversely the appropriate vector shuffles may cause this instruction to be generated. The other instructions are only generated via built-in support for now. Appropriate tests have been added. There is a companion patch to clang for the rest of this support. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@237499 91177308-0d34-0410-b5e6-96231b3b80d8
