5873b26a82 Speed up compilation process. 
bochs.h already not include iodev.h which reduces compilation dependences for almost all cpu and fpu files, now cpu files will not be recompiled if iodev includes was changed

ac4e5bb6cf - add sanity checks 
- don't allow MMX on cpu level < 5.
  - require FPU support on cpu level >= 55
  - don't allow MMX support without FPU support (moved this check from
    cpu/i387.h to config.h)

be659a09b3 - check in Stanislav Shwartsman's patch "bochs-mmx.patch-endian-support". 
He writes: Detailed description: MMX instruction set support.
  Also supports BIG_ENDIAN systems. Tested on Solaris and HP1100.
- modified files:
    configure.in cpu/Makefile.in cpu/cpu.h cpu/fetchdecode.cc
    cpu/proc_ctrl.cc fpu/fpu_system.h fpu/wmFPUemu_glue.cc
- added files: cpu/i387.h cpu/mmx.cc
