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".

These are needed for fixed-point math calculations.
Taken from the same public repo where we got the 32-bit divide
routines for Cortex-M0. With minor modifications to match changes
we've made so far for the existing divide routines (put each function
in its own section, delete dead code, etc.)

BRANCH=minnie
TEST=hack in a debug console command to allow arbitrary int64 divide, see that
it works as expected
