[AArch64] Add ARMv8.2-A persistent memory instruction ARMv8.2-A adds the "dc cvap" instruction, which is a system instruction that cleans caches to the point of persistence (for systems that have persistent memory). It is a required part of ARMv8.2-A, so no additional subtarget features are required. Differential Revision: http://reviews.llvm.org/D15016 llvm-svn: 254156
