21c9712ea2 * allow 32-bit operand sizes in the i8086 version of Tx86Operand.SetSize, so 
32-bit operands can work properly in i8086's inline asm. Fixes mantis #29188.

5c8965fea5 * in the inline asm reader, treat [var] reference as "word" instead of "dword" 
when "var" is of dword size. This fixes spurious generation of a $66 prefix
  and makes the code consistent with what Tx86Operand.SetSize does (and what is
  then used for checking the operand sizes of all operands of the instruction in
  Tx86Instruction.CheckOperandSizes).

42d251da1c - x86 assembler readers: cleaned out operand swapping code. Operands of TInstruction are kept in AT&T order, Intel reader attaches operands right-to-left. It was effectively the same way before the change (except Intel reader attaching operands left-to-right, followed by a single swap), operand order checks all over the place were just reducing readability.

4d0e4e1b56 * treat "[var + rip]" in intel assembler mode as addr_pic_no_got on x86-64 
(mantis #22665)
  + support "[var wrt ..gotpcrel]" nasm/yasm syntax in intel assembler mode
    for GOT-relative accesses on x86-64, + give an error when trying to do
    this on win64 (it doesn't have a GOT)
  * moved code that give a warning when using GOT-relative accesses to
    static data on x86-64 from the AT&T reader to rax86 so it's also
    active for the Intel assembler reader
  + added warning when not using GOT-relative accesses (but plain
    RIP-relative instead) to global data on non-Win64 x86-64
