4686f61002 * keep track of the temp position separately from the offset in references, 
so that they can still be freed after the reference has been changed
    (e.g. in case of array indexing or record field accesses) (mantis #33628)

518cdf9674 * replaced the saved_XXX_registers arrays with virtual methods inside 
tcpuparamanager, very similar to the existing get_volatile_registers_XXX. The
  new methods are called get_saved_registers_XXX, where XXX is the register
  type ("int", "address", "fpu" or "mm")

810acd82b2 * patch by J. Gareth Moreton that makes some improvements to the Peephole Optimizer for x86 and x86-64 code, as well as some cleanup with formatting, code syntax consistency, and debug messages. 
- xorq %reg,%reg (identical registers) is now changed to xorl %reg,%reg if doing so removes the REX prefix.
  - movw %bx,%ax; andl $0xffff,%eax, for example, is now changed to movzwl %bx,%eax as long as a conditional operation doesn't follow 'and' (checks to see if the CPU flags are in use).
  - movzbq and movzwq get optimised to movzbl and movzwl respectively if doing so removes the REX prefix.
  - Removal of optimisation code that zero-extends from 32-bit to 64-bit, because there isn't actually a valid combination of opcodes for MOVZX that allows that (for registers,
    just use  MOV). This is not the case with MOVSX.
  - movq is now optimised to movl even if the CPU flags are in use (this stops mov %reg,0 from being optimised to xor %reg,%reg if doing so breaks an algorithm that relies on them).
  - Fixed typo in peephole message regarding movq to movl (it said movd instead).
  - Made the peephole debug messages more consistent in formatting, some of which now have more detail.
* small fixes of the patch

ae92973196 + added support for the retw, retnw, retfw, retd, retnd, retfd, retq, retnq and 
retfq x86 instructions. These are variants of the ret instruction with the
  return offset size set explicitly, e.g. retfw is a 16-bit far ret (i.e. pops
  a 16-bit offset and a 16-bit segment), retfd is a 32-bit far ret (pops a
  32-bit offset, followed by a 16-bit segment), etc.

0fb79946a5 + added support for the parameterized versions of the x86 string instructions 
(movs, cmps, scas, lods, stos, ins, outs) in the inline asm of the i8086, i386
  and x86_64 targets. Both intel and at&t syntax is supported.
* NEC V20/V30 instruction 'ins' (available only on the i8086 target, because it
  is incompatible with 386+ instructions) renamed 'nec_ins', to avoid conflict
  with the 186+ 'ins' instruction.

92a52a9f4d + implemented support for instructions with non-native address size on i8086 
(16-bit and 32-bit), i386 (16-bit and 32-bit) and x86_64 (32-bit and 64-bit).
  Known bug: 32-bit addresses with an offset have their offset truncated to its
  low 16-bits on i8086

e701fa8de1 * converted the x86 instruction flags to a set, so they can be extended more
