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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205090 91177308-0d34-0410-b5e6-96231b3b80d8

ARM64: make sure first argument to INSERT_SUBVECTOR has right type. Again, coalescing and other optimisations swiftly made the MachineInstrs consistent again, but when compiled at -O0 a bad INSERT_SUBREGISTER was produced. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205423 91177308-0d34-0410-b5e6-96231b3b80d8
