This adds: - LLVM subtarget features to make all the new instructions conditional on, - CPU and FPU names for use on clang's command line, with default FPUs set so that "armv8.1-m.main+fp" and "armv8.1-m.main+fp.dp" will select the right FPU features, - architecture extension names "mve" and "mve.fp", - ABI build attribute support for v8.1-M (a new value for Tag_CPU_arch) and MVE (a new actual tag). Patch mostly by Simon Tatham. Differential Revision: https://reviews.llvm.org/D60698 llvm-svn: 362090
