On all non-x86 arches, runtime.abort simply reads from nil. Unfortunately, if this happens on a user stack, the signal handler will dutifully turn this into a panicmem, which lets user defers run and which user code can even recover from. To fix this, add an explicit check to the signal handler that turns faults in abort into hard crashes directly in the signal handler. This has the added benefit of giving a register dump at the abort point.
