*	Retrieve + print previous PC from stack to debug wdog/spurious IRQ	Min Xu	2014-11-11	1	-3/+15
\| \| \| \| \| \| \| \| \| \| \|	Retrive previous PC from the stack before entering specific interrupt handler routines. Allow user to trace where interrupt occured: e.g. WatchDog and Spurious interrupt Prior to this change, spurious interrupt would occur so much (observed via gdb/remote debug) so it appears that the board stalled. Once a custom spurious interrupt installed, the code continues after the interrupt instead of re-entering the interrupt.
