Kevin Lawton ee47fabac0 Committed new bochs internal timers (in pc_system.{cc,h}. 
These seem to be working better, are a more simple design,
  easier to understand, and AFAIK don't have race conditions
  in them like the old ones do.

Re-coded the apic timer, to return cycle accurate values
  which vary with each iteration of a read from a guest OS.
  The previous implementation had very poor resolution.  It
  also didn't check the mask bit to see if an apic timer
  interrupt should occur on countdown to 0.  The apic timer
  now calls its own bochs timer, rather than tag on the
  one in iodev/devices.cc.

I needed to use one new function which is an inline in
  pc_sytem.h.  That would have to be added to the old pc_system.h if
  we have to back-out to it.

Linux/x86-64 now boots until it hits two undefined opcodes:

  FXRSTOR (0f ae).  This restores FPU, MMX, XMM and MXCSR registers
    from a 512-byte region of memory.  We don't implement this yet.

  MOVNTDQ (66 0f e7).  This is a move involving an XMM register.
    The 0x66 prefix is used so it's a double quadword, rather than
    MOVNTQ (0f e7) which operates on a single quadword.

  The Linux kernel panic is on the MOVNTQD opcodes.  Perhaps that's
  because that opcode is used in exception handling of the 1st?

  Looks like we need to implement some new instructions.
