This patch adds a support of SIMD extensions of SPARC64 VIIIfx and IXfx (K Computer and Fujitsu FX10). It is for LLVM-3.9.1. Specify the target CPU as "-mcpu=s64fx8". It includes small patches to CLANG to accept a new CPU type (see in lib/Target/Sparc). Do not use this for SPARC V9, because the modification should conflict with the original code.
