Created attachment 13201
  --> http://llvm.org/bugs/attachment.cgi?id=13201&action=edit
proposed patch for llvm 3.5 -- trunk

There are some register Uses and Defs missing for several system instructions
(INT, INTO, SYSENTER/SYSLEAVE, IRETxx, PUSHCS16..POPGS64, VERRr..VERRWm)

I attached a small patch, that builds against LLVM 3.5 and git master
(0ba4483d01)
