Patch for fixing byte swap optimization.
I have tested this patch on i486-linux-gnu (C/C++ test suite only, full
bootstrap to be done). The problem was reported on m68k initially but I checked
that it also appeared on i486. The patched have been tested to work on
i486-linux-gnu and powerpc64-unknown-linux-gnu.
