arch/x86/exception: Print stack on exception
It's useful to see the stack when an exception happens so you can see
the variables on the stack, and also manually recreate the back trace.
If you need to recreate the back trace, you will need to add
-fno-omit-frame-pointer to the CFLAGS.
BUG=b:159081993
TEST=Caused an exception and saw the stack dumped. Then I manually
recreated the back trace.
