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: correct CodeGen of MOVZ/MOVK combinations. According to the AArch64 ELF specification (4.6.8), it's the assembler's responsibility to make sure the shift amount is correct in relocated MOVZ/MOVK instructions. This wasn't being obeyed by either the MCJIT CodeGen or RuntimeDyldELF (which happened to work out well for JIT tests). This commit should make us compliant in this area. llvm-svn: 185360

[AArch64][test] Add explicit dso_local to definitions in ELF static relocation model tests TargetMachine::shouldAssumeDSOLocal currently implies dso_local for such definitions. Adding explicit dso_local makes these tests align with the clang -fno-pic behavior and allow the removal of the TargetMachine::shouldAssumeDSOLocal special case. Split tiny_model.ll to tiny-model-{static,pic}.ll

[AArch64] Generate literals by the little end ARM seems to prefer that long literals be formed from their little end in order to promote the fusion of the instrs pairs MOV/MOVK and MOVK/MOVK on Cortex A57 and others (v. "Cortex A57 Software Optimisation Guide", section 4.14). Differential revision: https://reviews.llvm.org/D28697 llvm-svn: 292422
