Bochs/bochs/cpu/resolve32.cc
Bryce Denney 49664f7503 - parts of the SMP merge apparantly broke the debugger and this revision
tries to fix it.  The shortcuts to register names such as AX and DL are
  #defines in cpu/cpu.h, and they are defined in terms of BX_CPU_THIS_PTR.
  When BX_USE_CPU_SMF=1, this works fine.  (This is what bochs used for
  a long time, and nobody used the SMF=0 mode at all.)  To make SMP bochs
  work, I had to get SMF=0 mode working for the CPU so that there could
  be an array of cpus.

  When SMF=0 for the CPU, BX_CPU_THIS_PTR is defined to be "this->" which
  only works within methods of BX_CPU_C.  Code outside of BX_CPU_C must
  reference BX_CPU(num) instead.
- to try to enforce the correct use of AL/AX/DL/etc. shortcuts, they are
  now only #defined when "NEED_CPU_REG_SHORTCUTS" is #defined.  This is
  only done in the cpu/*.cc code.
