[PATCH] D34474: [RFC] [AArch64] Add a win64 specific aarch64 calling convention, for va_list handling

I'm still not sure I understand why we need the different CC when X86_64 is able to handle both the SysV and the MS style VAArg lowering via the ABI::LowerVAArg switching between the two.  I feel that we should follow a similar approach here.
