2653d54e96 split 32-bit modermdata variable in BxInstruction_c to 4 Bit8u variables 
this way it is possible to save shifts and masking when accessing modrm fields

494189e822 Small optimization for ADD lazy flags calculations. 
Because most likely flags are not needed after ADD instruction - it is better to store less data for lazy flags and reconstruct it if needed

56dd9fe3d9 - fixed several MSVC compilation warnings 
* MSVC doesn't support localized variables (e.g. valid inside of a 'for' loop
    only). So we cannot use the variable 'i' with different types (unsigned / int)
    in the reset() method.
  * added some conversions from Bit64s to bx_bool

6d7134ef99 Remove dump_cpu debugger function, CPI method and all related structures. 
Extended 'info' command in debugger to have all functionality of dump_cpu if needed. Also param tree print always could be used !

42fdd8a3a1 During Bochs benchmarking I figured out that hostasm actually slow down the emulation ... so remove this ugly code which also doesn't help :)

OK, currently I see big mess with setting of CS/EIP and SS/ESP everywhere, I have to unify it and make it easier !

082eb05b6b First step to fully configurable CPUID 
- put CPUID functions data into array, in future we could load this array from configure file
 - cpuid initialize function is more flexible now but still reuire some work

071c5c1a26 A lot of changes but everything is really trivial. 
Make save/restore default feature, the configure option for save/restore removed from configure script and save/restore made available forever. All code now assume it is exists. Bochs save/restore tree previosly called "save_restore" renamed to "bochs" tree and it will be havily used everywhere, starting from save/restore and ending by various bochs debugger functions. I am going to rework debugger code to get rid of debug CPU access functions and use this "bochs" param tree instead
