John Baldwin 2dce95a085 Change the i386 code to pass the interrupt vector as a separate argument
rather than embedding it in the intrframe as if_vec.  This reduces diffs
with amd64 somewhat.
- Remove cf_vec from clockframe (it wasn't used anyway) and stop pushing
  dummy vector arguments for ipi_bitmap_handler() and lapic_handle_timer()
  since clockframe == trapframe now.
- Fix ddb to handle stack traces across interrupt entry points that just
  have a trapframe on their stack and not a trapframe + vector.
- Change intr_execute_handlers() to take a trapframe rather than an
  intrframe pointer.
- Change lapic_handle_intr() and atpic_handle_intr() to take a vector and
  trapframe rather than an intrframe.
- GC struct intrframe now that nothing uses it anymore.
- GC CLOCK_TO_TRAPFRAME() and INTR_TO_TRAPFRAME().
