My previous commits were reverted in https://reviews.llvm.org/D28683, this patch reapplies them along with the fix from https://reviews.llvm.org/D28678 which has already been accepted. The only original addition that this patch introduces is a check in setARMSubArch to ensure that the CPU_arch attribute exists before trying to read it, as it would seem to be causing the sanitizer failure.
