[AARCH64] Enable AARCH64 lit tests on windows dev machines As discussed on PR27654, this patch fixes the triples of a lot of aarch64 tests and enables lit tests on windows This will hopefully help stop cases where windows developers break the aarch64 target Differential Revision: https://reviews.llvm.org/D22191 llvm-svn: 275973

ARM64: initial backend import This adds a second implementation of the AArch64 architecture to LLVM, accessible in parallel via the "arm64" triple. The plan over the coming weeks & months is to merge the two into a single backend, during which time thorough code review should naturally occur. Everything will be easier with the target in-tree though, hence this commit. llvm-svn: 205090

[AArch64] Prefer DUP/MOV ("CPY") to INS for vector_extract. This avoids a partial false dependency on the previous content of the upper lanes of the destination vector register. Differential Revision: http://reviews.llvm.org/D7307 llvm-svn: 227820

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
