  - Modify before_thread_runs_arch() to store addresses of the kernel stack and
  userspace window buffer, resp., to registers %g6 and %g7, resp, in the
  alternate and interrupt global sets.
  - Modify after_thread_ran_arch() to sample %g7 from the alternate globals.
  - Implement trap handler for spilling register windows into userspace window buffer.
  - Implement assembly language functions to access %g6 and %g7 registers in the alternate sets.
  - Initialize the trap table so that there are now also spill_1_normal, spill_2_normal,
  spill_0_other and fill_1_normal handlers. These handlers are used in different situations
  and for different purposes.
