Add support for AArch64 target. In cooperation with the LLVM patch, this should implement all scalar front-end parts of the C and C++ ABIs for AArch64. This patch excludes the NEON support also reviewed due to an outbreak of batshit insanity in our legal department. That will be committed soon bringing the changes to precisely what has been approved. Further reviews would be gratefully received. llvm-svn: 174055

AArch64: bring predefines in line with most recent ACLE document The prefixes and names used are now identical to 32-bit ARM, which is also expected to remain unchanged. If we made this change after a release, we'd probably have to support both variants for a while, but I think since AArch64 exists only on trunk now, it's acceptable to simply swap them now. llvm-svn: 178870

AArch64: 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: 187568
