ad01f059e8 * after a LdiMov/Cp2Ldi/Cpi optimization, the compiler should not continue to optimize this instruction because then reg. alloc info is wrong

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.

d318ab086a * when handling absolute vars from within intel inline assembly, take the 
absolute var size into account (not the type of the var it points to or no
  size at all, if it points to a fixed address)

d7e4b50068 + also optimize x86_64 references by switching [rbp+reg64] to [reg64+rbp], 
[r13+reg64] to [reg64+r13] and [r13d+reg32] to [reg32+r13d]

basically ignores these segments in long mode

e58bad8eef + check for the 'pop cs' instruction in the x86 inline assembler and print a 
warning (on the i8086 target) or an error (on i386 and x86_64) when this
  instruction is used (because it only works on 8086 and 8088 CPUs)

67a0e9bdae + added x86 helper function get_default_segment_of_ref, which returns the 
default segment base for the ref, in case there's no segment override
* in the internal assembler, use get_default_segment_of_ref to strip redundant
  prefixes, instead of always assuming all refs are DS-based
