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
