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

[ARM64] Change inline assembly constraints to be more lax, to match the behaviour of Clang/AArch64 and GCC. GCC allows sub-64bit values to use the 'r' register constraint. llvm-svn: 206963
