a8f466c400 * updated the CSeg, DSeg and SSeg rtl functions on i8086 to use the new x86 
intrinsics for reading the segment registers

29f307589e + added an i8086-specific procedure MoveData, that allows moving of far data, 
regardless of the memory model; procedure interface is the same as a similar
  Turbo C (and DJGPP) function

bc8c1ea1bc * fixed get_caller_frame() for win16 (on that platform, bp is incremented by 
one, before pushing, to indicate a far call, so it has to be aligned by 2
  again, after reading)
