[PowerPC] Initial VSX intrinsic support, with min/max for vector double Now that we have initial support for VSX, we can begin adding intrinsics for programmer access to VSX instructions. This patch adds basic support for VSX intrinsics in general, and tests it by implementing intrinsics for minimum and maximum for the vector double data type. The LLVM portion of this is quite straightforward. There is a companion patch for Clang. llvm-svn: 220988
