Make non-exception "software" panics such as stack overflow and assert failure save a panic log. Log the panic type in r4, and misc. panic data in r5 so that panic reasons can be distinguished. BUG=chrome-os-partner:36744 TEST=Manual on samus_pd. Run 'crash divzero' then 'panicinfo' after reboot. Verify that panic info is printed with "r4 :dead6660". Trigger stack overflow, verify that panic info is printed with "r4 :dead6661".
