I suspect this problem is now fully resolved. The patch for PR24427 has been
backported to the gcc-4_1-branch, and additionally on mainline, simplify-rtx.c
has been enhanced to also perform the missed-optimization at the RTL level.
Given that the 4.0 branch is now closed, I believe this is sufficient to close
this PR.
