This patch adds support for the next-generation arch15 CPU architecture to the SystemZ backend. This includes: - Basic support for the new processor and its features. - Detection of arch15 as host processor. - Assembler/disassembler support for new instructions. - Exploitation of new instructions for code generation. - New vector (signed|unsigned|bool) __int128 data types. - New LLVM intrinsics for certain new instructions. - Support for low-level builtins mapped to new LLVM intrinsics. - New high-level intrinsics in vecintrin.h. - Indicate support by defining __VEC__ == 10305. Note: No currently available Z system supports the arch15 architecture. Once new systems become available, the official system name will be added as supported -march name.
