John Baldwin 333b8de537 MFi386:
- Move PUSH_FRAME and POP_FRAME to asmacros.h and use PUSH_FRAME in
  atpic entry points.
- Move PCPU_* asm macros out of the middle of the asm profiling macros.
- Pass IRQ vector argument as an int rather than void * to reduce diffs
  with i386.
- EOI the lapic in C for the lapic timer handler.
- GC unused Xcpuast function.
- Split IPI_STOP handling code of ipi_nmi_handler() out into a
  cpustop_handler() function and call it from Xcpustop rather than
  duplicating all the logic in assembly.
- Fixup the list of symbols with interrupt frames in ddb traces.
  Xatpic_fastintr* have never existed on amd64, and the lapic timer
  handler and various IPI handlers were missing.
- Use trapframe instead of intrframe for interrupt entry points (on amd64
  the interrupt vector was already a separate argument, so the two frames
  were already identical) and GC intrframe.
