Tim Northover a2ee433c8d 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.

Amaury de la Vieuville 21bf6ed730 Do not emit undefined lsrh/ashr for NEON shifts 
These IR instructions are undefined when the amount is equal to operand
size, but NEON right shifts support such shifts. Work around that by
emitting a different IR in these cases.
