I've tried to reproduce the issue with rev 189549 (GCC 4.8),
GCC 4.7.2 20120711 (prerelease) and GCC 4.6.4 20120716 (prerelease).
It seems this is no longer an issue.

4.6 and 4.7 are failing with -fschedule-insns for me.  We changed
the default behavior so that -fno-schedule-insns is default.
4.8 doesn't fail even with -fschedule-insns.  I guess that your
patches for index addressing fix it on trunk.  Perhaps we can
close this PR because it's fixed on trunk and looks no hope to fix
it for 4.6 and 4.7 compilers with -fschedule-insns.

OK.  I think it's better to take any -fschedule-insns follow ups to PR 22553.
