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)
