AArch64/ARM64: move ARM64 into AArch64's place This commit starts with a "git mv ARM64 AArch64" and continues out from there, renaming the C++ classes, intrinsics, and other target-local objects for consistency. "ARM64" test directories are also moved, and tests that began their life in ARM64 use an arm64 triple, those from AArch64 use an aarch64 triple. Both should be equivalent though. This finishes the AArch64 merge, and everyone should feel free to continue committing as normal now. llvm-svn: 209577

AArch64: add initial NEON support Patch by Ana Pazos. - Completed implementation of instruction formats: AdvSIMD three same AdvSIMD modified immediate AdvSIMD scalar pairwise - Completed implementation of instruction classes (some of the instructions in these classes belong to yet unfinished instruction formats): Vector Arithmetic Vector Immediate Vector Pairwise Arithmetic - Initial implementation of instruction formats: AdvSIMD scalar two-reg misc AdvSIMD scalar three same - Intial implementation of instruction class: Scalar Arithmetic - Initial clang changes to support arm v8 intrinsics. Note: no clang changes for scalar intrinsics function name mangling yet. - Comprehensive test cases for added instructions To verify auto codegen, encoding, decoding, diagnosis, intrinsics. llvm-svn: 187567
