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] Enable alignment control option in front-end for ARM64. This is the modification in llvm part. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208074 91177308-0d34-0410-b5e6-96231b3b80d8
