[Bug target/40487] Extra zero extensions produced for ARM.

Yes, this bug is indeed not related to bug 39715.

I have also verified that the SEE pass (sign-extend elimination, but also
should handle zero-extend) fails to handle this case.  And that pass doesn't
exist anymore on the trunk anyway.

I wonder if we can optimize this in GIMPLE already...
