ARM & AArch64: convert asm tests to LLVM IR and restrict optimizations. This is mostly a one-time autoconversion of tests that checked assembly after "-Owhatever" compiles to only run "opt -mem2reg" and check the assembly. This should make them much more stable to changes in LLVM so they won't break on unrelated changes. "opt -mem2reg" is a compromise designed to increase the readability of tests that check dataflow, while minimizing dependency on LLVM. Hopefully mem2reg is stable enough that no surpises will come along. Should address http://llvm.org/PR26815. llvm-svn: 263048

ARM64: initial clang support commit. This adds Clang support for the ARM64 backend. There are definitely still some rough edges, so please bring up any issues you see with this patch. As with the LLVM commit though, we think it'll be more useful for merging with AArch64 from within the tree. llvm-svn: 205100
