Add support for backtracing across interrupt stacks, and add
interrupt frame backtrace for unhandled interrupts.
This requires a back-chain created from initial interrupt stack
frame to the r1 value of the interrupted context. A label is
added at the return location of the exception handler call, so
the unwinder can recognize the initial interrupt frame.
The additional cstart entry-frame is no longer required because
the unwinder now looks for frame == 0 as well as address == 0.
