Put the reason code in r0 and make a SVC #2 call, which will be propagated to _fatal_error_handler as an exception. The _is_in_isr() implementation had to be tweaked a bit. User-generated SVC exception no longer just used for irq_offload(); just because we are in it does not mean we are in interrupt context. Instead, have the irq_offload code set and clear the offload_routine global; it will be non-NULL only if it's in use. Upcoming changes to support memory protection (which will require system calls) will need this too. We free up some small amount of ROM deleting _default_esf struct as it's no longer needed.
