  SVN rev 216231 on 2010-12-06 15:15:27Z by kib
  
  Do not leak %rdx value in the previous image to the new image after
  execve(2). Note that ia32 binaries already handle this properly,
  since ia32_setregs() resets td_retval[1], but not exec_setregs().
  
  We still do not conform to the amd64 ABI specification, since %rsp
  on the image startup is not aligned to 16 bytes.
  
  PR:     amd64/124134
  Discussed with: Petr Salinger <Petr.Salinger seznam cz>
          (who convinced me that there is indeed several bugs)
