SErrors (formerly called asynchronous aborts) are a distinct class of exceptions that are not closely tied to the currently executing instruction. Since execution may be able to proceed in such a condition, this class of exception is masked by default, and software needs to unmask it explicitly if it is prepared to handle such exceptions. On DEBUG builds, we are well equipped to report the CPU context to the user and it makes sense to report an SError as soon as it occurs rather than to wait for the OS to take it when it unmasks them, especially since the current arm64/Linux implementation simply panics in that case. So unmask them when ArmCpuDxe loads.
