d1652093ac - applied some parts of the patch from Andrew Zabolotny <zap@cobra.ru> 
* changed all %ll format descriptions to FMT_LL macro so that
    Microsoft Visual C works correctly (it uses %I64)
  * missing type conversions added
  * cdrom.cc: variable types for win32 fixed
  * removed some unused variables in eth_win32.cc and harddrv.cc
  * added missing includes in make_cmos_image.c and niclist.c

a17d06abcb Optimized the main cpu loop iCache checks to remove a redundant 
check.

Commented out a number of instances of invalidate_prefetch_q(),
for branches which do not change CS since the EIP window mechanism
takes care of validating that EIP lands in the current page or not
in the main cpu loop anyways.

Fixed a couple cases (v8086 mode and real mode) of loading CS where
the EIP page window was not invalidated in segment_ctrl_pro.cc.
That may fix some aliasing problems reported before (OS2).

091052e199 - reverting to previous revision (xfer8 1.15, xfer16 1.21, xfer32 1.21) 
as it breaks AMD64 support.

b3d16a48ef - apply another speedup patch from Conn Clark. 
Notes from the author:
Here is another one of my speed up patches. Unlike my previous speedups
this one will help more platforms than just X86. It cleans up the Data
Xfer instructions. Since the Data Xfer instructions are the most often
executed instructions it gives a noticable boost in speed. The basic
optimization technique was to eliminate intermediate variables and pass
a pointer to the final destination or original source to the
read_virtual_whatever and the write_virtual_whatever functions.
